Me: careful with the lid on that milkshake! They fall off pretty easily.
Customer: oh ok thanks!
*2 mins later*
*customer storms back with half empty cup dripping with milkshake and slams it on the counter*
C: I dropped my milkshake in the car and it opened up and it’s everywhere! You have to make me a new one and I want you to pay for my car to be cleaned!
Me: let me just get you a manager…
C: NO I JUST WANT ANOTHER MILKSHAKE AND MY CAR CLEANED THIS IS RIDICULOUS!
Me: ….. *runs away to get manager*
*manager and customer have a heated exchange*
Manager: just make the guy a new milkshake for free I can’t deal with him.
*customer tries to throw it at me and misses*
*wonder to myself how I would’ve reacted*
This happened over 3 years ago and I still think about this often
