I agree with RB. I see it happen in San Antonio too, providers come in and expect to be booked solid and if they are not they leave cursing the city as a horrible town to visit. There is no excuse for guys pre-booking and NCNS a visiting provider because some ladies base their visit on pre-book appointments. However, it is unfortunately something that happens.
I think what RB points out is very true, I sometimes hesitate on seeing a visiting provider her first time she visits, because I'd rather see a local review, instead of going off her hometown reviews, just makes me feel more comfortable. A provider should take an first time not so great trip as a cost thing and perform up to her standards get some reviews and then give it another shot, if she wants to of course, and if it does not work out again, then yeah maybe the city is not for you. But I think bashing the city on the first visit just closes the door for future travels.
