Square holes are punched with drifts.
Early days working in a large hotel I was doing food prep with the Executive Sous Chef and a bunch of the other chefs. The Sous Chef asked me if I had ever been caught having a pull in the cool room. 17 years old I was shocked and quickly replied 'no, never'. To which he replied, 'it's a good place to hide isn't it?' I turned red and everyone else laughed.
