What makes the numpty behind you at the checkout think it's a good idea to start putting their shopping on the conveyor belt whilst you're still unloading your own shopping?
Don't get me started on the idiots who park at bus stops.......
I have been known to place some of my items amongst theirs - which confuses them completely. I was even accused of 'stealing her stuff' by one twit, until I pointed out that I'd be paying for it ...
Someone wanted to transfer some money from his UK bank account to my German one. So I pops into the bank to request my details ( Bic & Iban no.) so this transfer could be made.
She actually told me I wouldn't be able to do this because the UK had left the EU.
