I don't know if this is just me being bitter or what but I really hate it when customers tell me to smile and be happy. Like recently, we were understaffed and it was insanely busy. This lady as I am in the middle doing stuff in drive thru asks for water. So, me being me. I stopped and grabbed her water but I was distracted as I did. She stopped me from running over to help my co worker to tell me "smile, be happy." And I'm just like, that's easy for you say when you get to enjoy your day out.
