I worked at a take away shop in Australia (a Ma & Pa shop that sold fish, chips and pizza). The store was always closed on a Monday but the owner and a couple others would usually come on to do orders and prep.
The main lights were always off and the chairs are stacked near the door so you’d have to push past them to get in. But every time, without fail we’d still get a half dozen people pop their heads in and asking “are you open?”.
One day, the owner sliced his hand badly and had to rush to hospital. They took off so fast they forgot to lock the door and left the place unattended.
When they got back (very late at night), there was precisely one drink missing from the fridge, and $3 left on the counter.
