True story, I went to a supermarket around here one time, all the guy in front of me was buying was a small jug of milk. He just paid for it and left but left the receipt. So I went through the checkout with all my groceries and at the end the cashier gave me the receipt, but the other guy's receipt was still attached to mine, so when I checked the receipt it was a bit of an unexpectd surprise and so I just LOL'd when I saw all it said was "HOMO .99".
You never know how the computer scanner is going to abbreviate whatever we all buy.
