At risk of being redundant, I'll say again that experiences are highly inconsistent at these places and girls are expecting tourists or novice customers who won at the casino to stroll in and donate. There is great service out there for much less. Moreover, you want to leave feeling happy and not pissed off like you just toasted $$ in a slot machine. No matter how charming you think you are, there is no way your $100 is getting you more than 20 minutes of light back rub and HJ with some titty fondling if you're lucky. On a public forum, if you're asking my opinion, 19/20 girls you see there will not be worth the extra $ for 12 minutes of sex. I don't venture in to find the 5%. If you guys do see a stunning 18-21 year old at one of these borderline clip joints, lmk.
