Oh boy, I have LOADS of these! I'll stick to the work-based ones, otherwise I'll be here for days. XD
I work in a bookshop. The first thing straight ahead of you when you come in is a staircase. With a BIG YELLOW SIGN saying that books are upstairs And we get SO many people saying "I didn't know you had an upstairs!"!
We had a lot of trouble with people leaving the door open, so we got a thing on the top of the door that makes sure it closes. Makes a bit of a bang, but at least the door SHUTS. And people apologise! Every time! Srsly, guys, we don't mind the door going "bang!". We paid a man to attach a thing that would make it go "bang!". But it gets freakin' OLD listening to you apologising all the freakin' time!
We have more shelf space than stock, for a variety of reasons. Which means we get a lot of people using their most accusatory voice to demand "are you closing down?!". No, there's a recession on, and how would you like it if I came to your house and demanded "are you going bankrupt?!" in my most obnoxious tone of voice?
People who phone you, ask a question, then hang up without saying "thank you" or "goodbye".
People who don't start queries with "hello" or "excuse me". Surely it's only polite to get someone's attention before demanding "TRAVEL?!".
People in a completely different section of the shop who do that are even more annoying, 'cos I can't even hear them most of the time.
And recently, people have taken to coming into the shop and saying "I'm just going to look round, is that all right?". Um, this isn't one of those pushy boutiques, or a freakin' Argos. Of COURSE you can look around, and you really DON'T need to tell me about it!
Oh, and when you ask "do you need a bag?", they can't make up their minds or they give you a great big monologue. Or both! Seriously, just "yes please" or "no thank you". Don't care which!
I have a lot of rage at my job. I'll leave it there, methinks. XD
