I don't have a straw!

I couldn't stop myself laughing today. I know, I know, it is not very professional and nice of me to laugh at my work colleague....but what he told me today was hilarious!

He will be working this weekend on-call. So I said, "You have the short straw eh?"

He replied," What straw? I don't have a straw."

I was like huh?!

"I meant you are the unfortunate one that has to work this weekend," I told him.

He, then burst out laughing, and so did I. haha.

He said, "I didn't understand what you mean by straw. Guess it is just the way you say things here."
