Granted, it's a minor offense that's on par with the sales clerk in "Blondie" being amused earlier this week that Dagwood Bumstead was buying just one banana. Still...
...Earlier this month, I ordered from a drive-through. When the cashier asked me if I wanted my receipt, I said, "Yes." Instead of handing it to me, she crumpled it up and said, "Consider it filed. I hate receipts."
I'm still not sure what accounts for that attitude. I'm glad she didn't take that approach with the food, though.
