That's how you tell.

I seldom have a problem with that except for one time this gal did rush me, and I didn't see a clock around, but when she told me to get dressed I did so thinking she knew somehow.  When I finally checked my watch, it was fifteen minutes short.

I wasn't too thrilled with the service anyways, so I never saw her again.

Most times, I get a few minutes extra, or more

booked a lady (years ago) for 2 1/2 hours (her package, not my idea).  

first half hour spent in the hotel bar over drinks (again, her idea, not mine).

once in the room, we played for a while.  not the best, not the worst.

as we were sitting on the floor after a round or two, she casually asked, "so, do you want to take a shower?"

i looked at the clock on the night stand across the room, and pointed out that there was still 40 minutes left in the session.

40 minutes!

she made some excuse about not seeing the clock (which was interesting because she was sitting next to me, facing the same direction).

second worst example of this, happened to me about the same time.  i saw another lady for several sessions (she was one of the first i experienced in the hobby).  she had a clock in her play/bedroom, so everybody knew how much time had passed.

however after a couple of sessions i realized that she had it set to "bar time;" ie, it was set 15 minutes ahead of real time, to fool customers into thinking it was later than it really was.

needless to say, stopped seeing both ladies.

Rushing the hour.

I noticed many times that when the booker calls you to let you know that she is ready, is right on the beginning of the session time,then you walk to look for the apt and 5 minutes are over and the best one is when you walk into the bedroom and noticed that most of the time is 5 to 7 minutes ahead of the real time,so your session is cut short about 10 to 12 minutes,and on top of this they want you to cum faster,that's why I dedicated many years to trained myself to last longer in bed and get my money worth and now I just loved when they asked me when are you going to cum?,and I tell then when I want it!!!

Want To Avoid Being Rushed?

Don't pay upfront. Pay after the session is over. You'd be surprised how nice and easy going a provider can be when you don't pay upfront. If she wants money upfront, walk out on her. It's your money. Not her's. She has to earn it first.

I rarely if ever book an hour, and I always...

make sure I have leeway with my time on either side of a date. I don't want either of us to feel rushed, so I make sure we almost never do.  

As for a provider setting the clocks ahead, trying for the fast pop... who are you seeing? Check the time and keep it yourself. Go ahead and pop, more time for round #2. We control more than we often think we do, as clients.

If he experience is truly bad, we have the option to leave, review and not return

The research and reviews on this site is very important.

This way I don't deal with providers that rush, but give a great time on date.
 

and I see noting wrong with that.  One of my former Favs had a small travel clock...  after several visits I realized it was always in the room we played in.  I never caught her looking at it however & se was generous with her time.  

One of my earliest reviews...  I paid for an hour & she started with don't touch me here, don't touch me there...  have you cum yet?  Hurry up & cum!  I was back on the side walk headed to my car in under a half hour thinking I wished I'd stayed home.

They both gave me shitty numbers  the most recent of which tried to choke me and smacked me in the face which of course he left that part of of his review   the first guy was wicked early in the morning and his dick was like a coke can...i just wasn't into it or him and I'm sure it showed 😕
