I kinda like this one, from Streetfighter 2: "Go home and be a family man!" XD
The back room we have at the petrol station is small, crammed with stock but only stock that won't fit on the shelf, barring cigarettes which are locked in the cupboard and sometimes, if we're overwhelmed, don't go out. Some of my co-workers feel that if it's busy, then they can convieniently ignore the cigarettes, despite the fact that they're the easiest thing in the world to restock, as you can do so between customers.
Anyway, despite the smallness of the back room, a lot of customers are determined to believe that we keep a Tardis back there.
