What goes around comes around

I went into Nyiregyhaza to go shopping today and to buy my train ticket into Budapest. When I went to get in line at the ticket counter, a guy was changing from another window to the window I was approaching, and as he seemed to be in a real hurry, I signaled for him to go first. He was still putting away his ticket, etc., when I approached the window and he heard me speaking in English and asked if he could help. He then stood there the whole time and assisted with the transaction! Don't know why he wasn't in a hurry anymore, but I thought that was real nice of him!
