Cool I'll watch out for SG slashers that hang out over by the area your talking about. Some of those girl look really young, so it's a good idea to make sure they have a health card in that area.
I wonder why JuanDavid you just didn't call the whole thing off when she didn't even give you her name, and had that all business attitude? I know when I get a really bad vibe, I just call the whole thing off, and send the chica packing, and I usually get my $12 dollars back too or I get credit, but with SGs the rooms are only $5 dollars, so if a girl ever acted like that, I'd throw her out. With SGs you mostly have to pay first, but still sometimes it's not even worth the effort of trying to get your money worth.
But on the other hand I had a few young looking SGs with nice bodies, act a little bit like that, look at her watch, or ceiling and it didn't bother me one bit, and I would even kid with them, you don't like sex? Well I do, and told her have fun looking at the ceiling because I'm going to enjoy myself fucking her near lifeless body while her head is someplace else.
Maybe she was a Mexican 'EMO" chica?
