Is someone on my team was hit on the head by a falling gallon of milk and was drenched, I would let them go home to shower and change, Black Friday or not. I would also encourage them to fill out accident paperwork and go see a doctor, since any head injury can be serious. Depending how far that milk fell before hitting the person, a concussion or neck injury are possibilities. Better safe than sorry.
OP, sorry your store “ leadership” treated you like that. Congrats on your new job and good luck!
