We've all seen that in a few reviews. It happened to me recently with a couple of providers (one gal tried it three times). In each case, I got a text with this request when I was 5-10 minutes away from arrival. Of course, the gals already have condoms. They are assuming you will have to make a stop to get them, so this buys them 5-10 minutes more to finish up with the customer they are with.

This shouldn't deviate someone from their plan... I'll take this as PSA.

that's what you are going to get..  Try seeing a higher end provider and she might just have the business acumen of providing a condom.  

But get there on time and see how long you have to wait. You might have to wait 15 minutes. If you have to wait longer, tell them you are cancelling because the wait is too long. Had to do that a few times with BP providers. You usually run into this when they are sharing a hotel room.

I do carry them and did arrive on time, and did not get a callback for 10-15 minutes. When she tried it again, I told her I knew what she was up to and left. That is why she is a fomer ATF.

This provider first asked me to buy her a bottle of lube then for the next date she asked to get her
 some baby wipes. I realized she was trying to use me and have not called her since.  

... or maybe not, perhaps your previous scheduling with her was usually spot on.

Remember his incident with a non-BP provider?

I learned this in Thailand.  They will always use condoms but in Thailand they purchase the cheapest ones they can get.  I have met a few US providers that always use Magnums just in case the guy is huge.  I am secure enough to publicly admit that a Magnum is a bit....well.....ROOMY for me.  LOL  So I take my own anyway.  LOL

Whether they had condoms and lying, or they did not have condoms because they were sloppy, its still poor business practice, and can be directly co-related to how BP girls operate.

I always bring my own....

Ask a gent to stop and pick up my supplies for me.  While I do enjoy myself, and consider myself lucky that I get to have such an amazing opportunity, this IS my business and that strikes me as very unprofessional.  Especially if it's happened to you several times.  I am very low volume and selective in who I see, but it sounds like you are visiting with girls who do back to back appointments... Perhaps consider a change in your provider choices?  I don't know any man that wants to arrive while some other gent is hopping off and walking out.  Ewww...

This was an agency, though.  Asked to pick up a box, but was paid off in spades.  One of my best sessions ever.
