Well, I stole HBO, Showtime and Cinemax in college 'cause the BF knew how to tweak the cable box....
More recently, (maybe 3 years ago) I was on my way to a party and was in charge of picking up supplies. I had a grocery cart filled with chips and chicken wings and asortable munchies and mixers.
On the bottom part of the cart I had three "suitcases" of beer stacked up (72 cans in all...) And as God is my witness I forgot they were under there. Amazingly, the cashier and the bag boy didn't notice them either, and it was only as I was on my way out of the parking lot that I started adding up the total bill in my mind... Sure enough, they didn't charge me for them.
Now, if I was Abe Lincoln I would have turned my car around, walked back into the store, explained what happened and paid for them.
I'm not Abe Lincoln.
