Backstory: I'm the only waitress at a small restaurant. About two weeks before making this post, we had a creepy customer who was very flirtatious towards me (even after I told him I was both taken, and gay) throughout his meal.
He stayed in the restaurant for a very long time, basically making my entire night uncomfortable, and was finishing up his last drink when it was time for me to go home. Hoping to stall him and avoid a confrontation in the dark of night, I wrote up his bill, told my manager that the bill was for that customer and asked him to please handle it for me.
I then quickly left, somewhat worried about the creepy guy. Unfortunately he came out of the restaurant and started following me, still flirting, so I walked to the local taxi company (which actually has their main lot right below my apartment window) and asked them to drive me around the block a few times, which fortunately allowed me to shake off creepy dude (and taxi driver didn't even make me pay for my ride when he found out why I'd asked him to drive in circles).
When I arrived back at work the next day, I found out that creepy dude hadn't paid for his meal. He'd told my manager I was his friend and that I was going to pay for him. My manager believed him, and I had to pay for the guy's whole meal (about 50 bucks, which is a lot for me since I'm on minimum wage and I don't get tips).
Today, creepy dude came back. Once again he was unpleasant and flirtatious through his whole meal, and stayed for a long time, basically ruining my day. At the end of the day however, I stuck his meal from two weeks prior onto the bill in addition to the meal he'd just had.
When I brought him the bill, I saw a look of defeat cross his face a few moments after he looked at it. He ended up paying for both his meal, and the meal he'd skipped out on last time (so I got my money back, yay) without a word of complaint, and left quickly after, not saying a single thing to me or my manager, unlike his previous talkative self.
