In my last year of university I worked at a sports bar, which was a lot of fun - great atmosphere, relaxed, easy job, decent money, and an AWESOME management team that I was very appreciative of (and vocal about my appreciation).
I was told on my first day that we are not to tolerate abusive or aggressive behaviour and that if a customer touches us, we are expected to leave the table immediately and get a manager or supervisor. It was made abundantly clear that these were not suggestions, but RULES, and that management takes that kind of thing seriously. I thought, OK that's good, but I doubted they actually cared that much.
Well, I was proved wrong one shift when I had a table of men in their fifties in my section that I found obnoxious and creepy and who were drinking quite a lot. A few off hand comments were made that I just sort of rolled my eyes at and ignored. Then one of them intentionally dropped a fork on the floor and asked me to pick it up, so I did and when I was bent over he groped my ass and said, "Yep - as firm as it looks!"
Caught off guard, I jumped up and made a little "yelp" type of sound. They all laughed and I was fucking livid.
I walked away immediately to approach my manager, but he met me halfway, as he had seen it happen. He told me I could go out for a smoke if I wanted and he'd take care of the situation, and also promised that my tip wouldn't be affected.
Well, to be honest I was curious to see how he would handle it, so I stood by the bar and watched as he walked up to the table, bill in hand and a portable credit/debit machine (I guess he'd printed it when he saw what happened, intending to go over there whether I said anything or not) and told the guys it was time to pay up because they had to leave.
They tried to put up a fight, but he was having none of it and launched into a red-faced tirade about how he had no patience for these types of ass holes and his employees deserve to be treated with respect, that they can't just run around acting like a bunch of animals and expect to get away with it, etc. He took the guy's credit card and swiped it, told him to put in his PIN and then took the machine back before it got to the tip screen.
The guy was like, "What the fuck? I'm not done yet!"
My manager just laughed and said, "Yeah, well I'm making sure my girl gets her tip." He rang through a 25% tip, handed the guy the receipt and said they have to leave immediately and were not allowed to come back.
That guy was awesome :)
