experiences good or bad?

my bro's girlfriend says someone in their work that was out the other nght likes me n wants to go out but they won't tell me anything else. I know I should just go along but the fact they wont tell me anythign is leading me to believe that they're taking the piss and setting me up with a fairly unnatractive lady from her work that I pulled that night. I wouldn't have a problem just walking right past her and not saying a word to save me a crap night out to be honest but it would make me feel kinda bad.

so blind dates: always absolutely shit where you end up smashing a wine bottle over the dates head 10 minutes into it thus ending the date or can lead to cool stuff like wild horny sex which may or may not include handcuffs and fruit or something a bit nicer like a proper relationship/
