I just remembered this for some wierd reason today, as it happened probably two years ago.
I was working the box office at my theatre, not a terribly busy night. I was in a good mood, and this trio of 20-somethings (2 girls, 1 guy) come up to my till.
They order their tickets, I tell them their total. Guy says, "Ouch, that's harsh! Not even so much as a hug first?"
Since I have a warped sense of humour, and was in a good mood, I offered him the hug.
He took it and so did both the girls he was with (and they were cute too!
