i work at an apple service provider. we had a customer come in to see if we could help with their ipad mini. it was bent. almost in half. and apparently it had happened by itself. my colleague explained that it's now considered out of warranty and the customer wasn't happy. they started to walk out muttering about poor service and paying a lot for the product and then it happened. 

i wasn't even dealing with this customer but for some reason the small child in me thought "hey, i know what would be a good idea" so as they were half way out the store out of my mouth came, and quite loudly "have a good day!" with plenty of sarcasm intact. 

they stopped. turned around and my god i almost shat myself. they asked my name, which i gave, and left in rage. so here's hoping they forget to email/ring our customer service line...

TIFU by telling a customer to have a good day.
