My Delivery Guy Decision

I had to make a quick decision on whether to tip a South Jersey delivery guy yesterday, due to what he said.

When the delivery guy drove up to my apartment building, I received a phone call that he arrived.

I walked downstairs.

I greeted him at the front door.  The first thing out of his mouth was "I called you, I've been waiting here 10 minutes."

At first, I looked at him puzzled.

Then he immediately changed his story as he said, "Five Minutes...I waited".  (I guess he decided to be nice and cut the wait time)

I responded with "I literally just walked down the stairs, and it was only two minutes.", followed by some sort of sarcasm.

I tipped him five bucks.

A part of me regrets it.
