common courtesy

I went to my local branch (GOODWOOD, WC) to get a proof of address form the ATM (as I usually do)... the atm's printer was offline - so (that this stage the branch had just closed and there were still client's inside). The roller shutter was already down. So casually asked guy sitting behind the shutter if there's a way he can help me (I can use the self serve station) - his response was nothing savoury...and anything but friendly
