I've yet to encounter such a person. Besides the Arby's incident and the more recent one I described at McDonald's, there were too many other incidents.

I was in the middle of lunch at Applebees (before the pandemic) and two ladies was just being seated by the host. They requested a booth and there were no booths open. I just happen to be occupying a booth by myself, so I gave my booth up for them.

I didn't even get a thank you. They acted snobby and said they'd take my booth if it's clean. Like seriously?

And btw, if it weren't so busy at McDonald's and if I didn't have my GM helping me cope, I doubt I'd ever get over the customer being so rude. If people mostly appreciates being treated nicely, then either this particular customer isn't "people" or I'm having bad luck.
