One time a few years back I was out with some friends and these girls were getting a bit rowdy, ordering all kinds of drinks and food then giggling and whispering. So I asked what’s going on and they told me they were planning to dine and dash. I was so pissed because I have worked in the service industry and I hate when people rip other people off of their hard earned cash. So I secretly paid for their bill and I told the waitress that the girls were going to do the tip. She was pissed that I didn’t give her a tip, but at least the bill got paid. To this day I don’t think they know that I did that
