(A middle aged couple comes to my checkout.)

Me: “Hello, how are you?”

Wife: “Fine, thank you.”

Husband: *grumbles*

(I proceed to pack their shopping, when suddenly the male customer starts looking angry.)

Husband: “I think you hate your job! I think you want to quit!”

Me: “Um, no… I quite enjoy it.”

Husband: “Well, you will get fired! You don’t show a proper respect!”

Wife: “Henry, calm down.”

Me: “I don’t know how I offended you, sir.”

Husband: “No, not to me! Show proper respect to those biscuits!”
