Man, I've definitely seen these guys, in every store we service, leave the damned door open. Granted, their job doesn't look fun either. But CLOSE THE F#%KING DOOR!!! Same with the girls in the store; they get busy, they leave the walk-in cooler or freezer door slightly ajar. Ya know, all you can do is politely remind them that they are causing their own problems in these circumstances. And when you get called out in the middle of the night over it...Well, it's job security I guess.
