If you work at a gas station (or in retail at all)

What's one thing that just annoys you about some customers?

Mine is when they come in and point to the pump and say "I'm not sure what pump I'm on, but I need ten in gas. It's the white car" and you look out and there's 5 white cars 😒

Or "can I get this today and pay you on Thursday?" and when you say no they tell you the owner said ok, and so you call the owner, who says they never said that and then the person gets mad because you didn't believe them. Well sorry, but this isn't my store to give you items on credit, you can come back on Thursday to get your cigarettes.
