I had asked the cashier to break $100 and the guy behind me pulls out his wallet and says "oh, you don't like carrying around big bills?" while pulling out $500 and waving it in my face. Ok, so then she's counting out change and he made a comment about hoping there was still enough change for him. I was trying to put my bags in the cart and put my money away and he was inching closer and closer and twirling his keys around his finger and shaking them in front of Eloise and he turned his key fob around so she could see it and said "look! B.M.W" while pointing to each letter.
