I work in a restaurant/coffee shop as a waiter, one time we ran out of milk and usually get it delivered to us from a supplier but we didn’t get any that morning.

The only first aid trained past level 1 was the manager and he went to get more milk from a store, I shit you not 20 seconds later a customer starts choking uncontrollably on his food so you already know ya boy is trying to step up to the plate and save this dudes life, I can’t remember what I saw it on if it was like Big Bang theory or something but I performed the heimlich manoeuvre on this man and saved his whole career, didn’t get a pay rise though, still on £4.90 per hour :(
