I was told to hide expiration dates
I received product that had expired and repacked it for disposal. The large quantity of potato chips (crisps) that could not be sold concerned my manager enough for him to make a call, whereupon he was told the date had a printing error. The manager instructed me to place huge, circular stickers directly over the expiration dates and market them.

I refused. He didn't argue and took on the task himself.

On the other hand, I've been asked to ride on the bare forks of the lift truck 30 feet high and did so gladly. (Jumping up and down on the forks at full height tends to piss managers off. Ha! When I die, I won't have to do this job anymore.)

In a convenience store
near where I used to work, the guy that ran the place would scratch the sell by date off of chocolate wrappers (and god knows what else). Thankfully we knew this so we would rifle through the display until we found a bar with a legitimate date on it. I guess this sort of thing goes on everywhere!
