A recently overhead conversation:
Guy #1: "Sometimes I pretend I'm gay and flirt with homosexual men to get better service. For example, I'll chat up the airport shuttle guy so he'll drop me off first..."
Guy #2: "Dude! What the f***???"
Guy #3 to Guy #4: "Y'know I would've just slipped the driver $5"
Guy #4: *shrugs*
I don't think it's right to lead people on, regardless of your sexual orientation, especially if you're not genuinely interested/available and are doing so just to take advantage of the other party. It's all fun and games until somebody gets hurt.
