Seriously those things and half the other equipment at a fast food place basically has to be emitting alarms at DBs that are known to cause hearing loss and mandate hearing protection in basically any other line of work.
Amazon trucks now sound like a garbage disposal because people got too annoyed when they'd back away but god fucking forbid fast food workers don't have to fall asleep with the monotony oh hours of beeping stuck in their head. Oh and the headsets will make you go deaf because you need them on max volume to HEAR OVER the fucking BEEPING
