i worked at all the pizza chains delivering ---- the absolute shittiest ones were a nightmare, for the same 3 reasons:
not letting employees make food themselves. it’s a restaurant, you have abundant food, it’s cheap, we all know it’s cheap, we work long shifts, come on. the cobbler’s son should have good shoes.
overemphasis on dress code – if you genuinely give a shit if the pizza guy has his hat backwards, you should literally be sent to the gulags.
being overworked for low pay, especially being made to drive when exhausted [literally dangerous and life threatening!!]
