Sorry to break up your "fun" guys but amy looks very young so men like you should be educating and protecting instead of leering and sniggering or do you think I'm wrong?
"Why do some blokes think it's ok to grope waitresses?"
2sp they're in a testosterone fueled enviroment, usually drunk, have money and feel all powerful and invincible and when men are in that scenario it seems to awaken a primal neanderthal instinct where the men are "In control" and women are 2nd rate and the waitresses are usually walking around close enough for them to suddenly grab without thinking.
We downplay it and call it a grope when in fact many times it's actually a sexual attack. Picture this in the club, out of a group of men one grabs the waitress and tries to kiss her then the friends or security break it up, the man just laughs it off and the waitress is traumatised if she's new or shrugs it off if she's an old hand.
Now picture the man grabbing the waitress for a kiss but now take away the club, take away the friends and put the waitress and drunk guy in an alleyway and now what do we have? Yes a very dangerous situation with a strong intoxicated man and a scared woman.
Sad but this and worse goes on everywhere every night even daytime as well
