Oase usually isn't as bad as Palace for upsell, but I guess if some girls see a guy in their club for the first time, they try it on, hoping he is a clueless newbie, it's got to the point in many clubs where you need to interview what services she'll do before you go into a room, couple of years at Paradise in Stuttgart, took a sexy Czech to a room, as soon as the door shut she came out with a list of extras, I just put my robe back on and walked out the door, you never know, down in the lounge she was nice girl and friendly, obviously took me for a mug. The choice in Frankfurt is both good and bad, it being the financial city of Germany, the clubs especially Palace attract so many clueless businessmen and tourists, but if you like the fake tit barbie type then it's a place to go, Oase can be hit and miss like many clubs, had some good punts there as well as average ones.
