To be fair some of these that appear rude are just celebrities establishing boundaries.

I met AJ McLean from the Backstreet Boys at work once. Walked up to him, extended my hand and told him my first and last name and then walked away. Like we were in a business meeting and had just closed the deal.

First things first, I am not a celebrity. I am, however, recognizable and a classical singing student. I was at the groceries with my mom a month or so before the pandemic hit, when two girls, I'm guessing 7 or 8, came up to me and asked "are you the lady who sings opera at the school [of Fine Arts]?" I got very flabbergasted, my whole body was shaking and said an almost inaudible yes. Yhey sighed with admiration or something and asked for a picture. Somewhere there's a picture of me with two kids in front of a shelf of floor cleaning products. I went full shy Patrick Star after their parents walked away with them. Couldn't even move, I had a mix of what in the world?! with YOU LIKE ME, YOU REALLY LIKE ME! It was a very awkward and thrilling experience.

Back when Brad Garrett was doing stand-up comedy, I accidentally dropped a full #10 can (~1 gallon) of cocktail sauce on his brand new Tony Lama sharkskin boots. The guy's built like an oak tree and I thought he was going to slaughter me but he was nice about it. He said "It's okay. It's ooookay" in that distinctive basso profundo.

I met David Cassidy, a dream for my mom. He allowed us to take a picture which was nice then snapped at us and others that we weren't holding the papers straight enough for him to autograph quickly. I appreciate him taking time to do this but he snapped at a lot of people for a lot of small things. I met Patula Clark there too and she was lovely. Chatting with everyone and full of compliments and nice things to say. Quite the contrast. Maybe we just caught him on a bad day sometimes we forget that they are people too
