Holy crap, wtf kind of hell hole do you work in? Satan’s Anus and Sundries Emporium sounds better.
Where I work, there are all sorts of rules everybody ignores. Don’t smoke in the trucks, sweep out the back and refuel before parking for the day, no beverages in the warehouse, things like that. The only diligently observed rule about phones is “no phone use while driving” mostly because it gives people an excuse to ignore calls from the office.
