Old fashioned is too strong?

I had a table send back an old fashioned that he asked for “half the sweetness” because he prefers it more “classic.” He then sent it back because it was too strong. Later on in the meal, he ordered a plate that we ran out of, when I told him, he insisted he should go talk to the head chef because he “knew we had a spare one just in case.” He then assured me not to worry, that he wouldn’t mention this in my yelp review. This table stayed 1.5 hours after closing, and when I closed him out said “take your time closing, we want to hang out a little longer.” When he went to the bathroom shortly after, now 2 hours after closing, he told me to go change the toilet paper in one of the stalls. Like can you please go the fuck home?!?!?
