‘In line at the drugstore…’

In line at the drugstore it’s finally your turn, and then it’s
not as he walks in front of you and puts his things on the
counter. The cashier says, Sir, she was next. When he
turns to you he is truly surprised.

Oh my God, I didn’t see you.

You must be in a hurry, you offer.

No, no, no, I really didn’t see you.
