Soldier 1: I'm about to deploy to a combat zone and I couldn't get a new helmet from supply.
Soldier 2: Out of stock, huh?
Solider 1: No, they had five of them in my size but said I couldn't have them. Their new regulations state they are always "required to have five in stock at all times" in case someone needs them.
Soldier 2: What a shoeclerk!
