Laziness Is The Sister To Bickering

(I work in a small shoe shop with three different storeys to store the shoes. It is a very old building with a lot of stairs. A customer wants to try on a pair of shoes that is stored on the top floor. There are only two of us working.)

Me: *to my colleague* “You go get it; I went up last time.”

Colleague: “Why should I go and get it? You go.”

(We bicker for a moment, and I realise how this must look to the customer. I turn to address her.)

Me: “We’re sisters.”

Customer: “Ah, that makes sense.”
