I haven't done that, myself, but my sense and expectation from being around here for a while is that it's considered time on the clock (or off the clock, whichever one means, "yes, you're paying!) The general rule is you're paying for her time, regardless of where you are and what you're doing.
Some ladies start the clock the minute you meet at the bar, others not until you get to the room. While reading this lady's reviews, did it mention she was strict about her time or did the reviews state, the old NOT a clock watcher. Next time, you want to meet a lady in the bar before you date ask. You've hobbied enough to know never assume anything.
Seriously, ask if the clock starts when you arrive and shake hands or when you get to your room. It is non-incriminating information and I have never been told off or hung up on by a lady when inquiring. Often, without even asking, the agency or girl volunteers to make it OTC (free) while we dine or drink together. Then again, I generally book 2 to 4 hour sessions so giving me an extra 30-45 min while we eat or drink probably isn't that big of a concession.
Oh yea, and being a regular cannot hurt either! (Still working on getting my 13 girl rotation up, but for now, I have 2 quality girls and see them semi-regularly...so perhaps they are more lenient on the clock because of repetition...dunno, filmatleven.)
It's an old cliche but it's the truth. Unless you have an established relationship with a regular lady you should assume that the clock starts when you meet her. Drinks, lunch, dinner, before or after the sex are generally on her clock. Now, once you become a regular that my or may not change.
My fave lady, our first time, we met at Hooter's. Had a drink with her while she finished her lunch. But play time didn't start until we got to her incall. You just got screwed, and not in a nice way, IMHO.....

He didn't get screwed over. Some will do drinks OTC, but it should not be expected and you're not entitled to free time with a provider.

Some ladies post on their site that they will meet up and have a drink before the session..but those are not common (at least not on the Chicago side). I would always approach my session as starting when we meet (wherever that might be). It would be awfully presumptive to think she has set aside an hour extra just for you.
More common would be after the session if you and she want to go for a drink (or lunch/dinner). If I had a really good time then will make the offer, some go for it, others not. Either way I don't take it too seriously whichever route the post session goes.
and then the guy balks... so she gets primped & preened, full makeup, dressed up (figure an hour of prep (all on her) PLUS the date time (maybe just a half hour for a drink), and then might not get a paid meeting out of it!
That said, each lady must run her business as she feels is best for her. Some will be more lenient... some not. You are compensating her for her time. Most say you can use the time anyway you choose. If you want to sit in a hotel room & play cards... it's your time. (Strip Poker, maybe! LOL!!)
This is one of the wild cards of the hobby, but she did not scam you.
happy hobbying

Thanks, gents! All great advice and good for newbies to hear.
I agree, the bottom-line to learn here for me (again) and for all newbies is assume nothing and ask polite questions up-front about what you're getting since it's your money and the provider's time.

I think what you experienced is the norm--all the time together counts.
I have had many dinners and most have been on the clock, but maybe 25% have been off the clock. Usually the more often I have seen a lady the more likely dinner is OTC, especially if it is after the scheduled time.
It used to be that some ladies would actually require 15-30 min over a cup of coffee or a dring at the beginning of a 1st date. In those cases it would be the last part of the screening process, it was OTC, and either side could opt out if they felt it was not a good match. I do not know any active ladies who do that any more.
The bottom line is you are paying her for her time. So any time you use counts against you. However, there will be some ladies who will not take into account times such as this.
What I do is offer "dinner dates" or "get to know me date" where drinks or dinner is included in the time so they get the full 2hr or 1hr they want for "alone" time but we get to know each other through drinks or dinner at a lower rate than my normal rate since we are only talking after all 
If a client doesn't ask for this package I usually count some of the time. So if we talked and drank for 30min I take only 15min off the total time(although I never really watch the time anyways)
Next time ask a provider before if meeting for drinks will count against your time together. Can't hurt to ask! But to answer your question yes, this is very common practice since as I stated above you are paying an escort for her time.
