I'm not guilty, with an explanation:
Wasn't home during the alleged transgression.
We went out with friends to watch the game last night. A friend that's notoriously cheap.
It was their turn to pay. As we were walking out the door, (I went ahead to warm up my truck)
My wife overheard the waitress ask my buddy "Are you sure everything was OK?"
So we figured he didn't tip fairly, at all.
I tried to wait in the parking lot until they left, to go back in and set things right. But they sat in their car talking.
Long story short.
I'm going back today to "tip" the waitress.
