I was making an absolutely nightmarish trip down to Colchester from Sunderland in the very North East of England (google map it, it's a pretty long way) and my mate's sat-nav was taking us the long way (which incidentally would end up taking us about 8 hours) to see one of my favourite bands, cKy.
About 5 hours into the journey, we were all feeling a bit down and fractious so we stopped at a McDonalds to get some spirit lifting cheap food. We came through the drive through, made our order and were told to park in one of the spaces to wait for our food. 20 minutes passed. 3 other cars parked next to us and drove away before one woman came out with a brown bag towards our car, much to our jubilation.
My friend turned on the engine as we began to dish out the food, only to realise we had been given completely the wrong meals. Nothing was right at all. At this point my mate Dave totally flipped his shit, climbed out of the car, walked into the restaurant and proceeded to throw the bag at the woman behind the counter.
At first he simply informed her that they gave us the wrong order, to which she persisted in saying we had been given what we ordered, at which point he screamed "I DIDN'T ORDER A FUCKING FILET O FISH!" and tossed the receipt at her. Upon reading it the woman began hurriedly apologising and offered us some free McFlurries, which we were forced to decline because we were in a rush.
We ended up getting our food which was just the thing to lift our spirits and scared the hell out of some employees. Greatest McDonalds ever.
