Give me some SEKs

I was on a training-course in Sweden last week. We were waiting in a que for lunch. My girl-collegue already got her lunch when she realised, she had forgotten her purse upstairs in the training-room. She asked loudly our boy-collegue: Would you kindly give me some SEK-s? (Sweden crownes).

I suppose, this is a hot candidate for a long-live joke in Sweden.
