history: There was this one time I was with my friend, and there was this customer who was being rude. We looked at each other, and had the same thoughts without saying out loud to each other.
current: One time I went out to eat with my friend. And there was a customer who was just very rude and vulgar. My friend and i gave each other "the look" and realized we were having the same thoughts. I was surprised. 
next: (Thank you for your words! I have a mom to talk too, so it helps but loads of trauma, abuse and death are hard to even talk about. Thank you! I hope you feel better too!) I have had to talk to customers who were nasty to clerks before! It's shocking.
