I worked in a fairly nice restaurant during the day as a bartender. We'd have the busy work crowd and then it was just me for the rest of the afternoon before the night staff came in.

Sometimes it was dead but usually I was pretty busy because I was serving tables, running food, making drinks, manning the floor, you know all of it because it was just me.

There were these 2 guys who would always come in around 3. They'd order the most complicated possible drinks and then laugh at me because it was taking so long, especially if it was otherwise busy. They'd pick on me if I was serving other tables and took a while to get to them.

At least they tipped well.

But finally, one day, they were vaping in the bar and making inappropriate comments to another person of a different ethnicity sitting at the bar. I was ready to say something but thankfully my manager came up at the right time and very sternly told them to leave and not come back. So that was the end of that.
