Being a cashier I deal daily with customers who think they're the first person to say the following things. More than likely this is a part one list.
  1. I got more than I expected!
    Usually said when one has overfilled their cart
  2. You look like you're looking for something to do/ you look bored.
    They clearly are not good at reading facial expressions
  3. The one guy who always replies to "how are you?" with "still on the right side of the grass!"
    Please dude, come up with something else!
  4. It's a beautiful day outside!
    Yes, I am well aware that I am working and you're not. Shove it.
  5. (When going through the express lane) I might have more than 14 items.
    That's what the regular lanes are for, douche.
