just ask yourself if you owned a petrol station would you insist on people taking off their helmets or would you be happy to let them in with a helmet on?
I have been asked to remove my helmet by a night cashier who was
locked inside the kiosk, when I was outside pre- paying by card.
This is the trouble with making sensible rules ostensibly designed to protect people and property, they get interpreted by non-sensible people to mean whatever they feel like making them mean. Sensible rules become silly when applied by non sensible people.
That's why in my view it's no bad thing to challenge them, otherwise they'll introduce more and before you know it you'll live in a world of increasingly petty rules. (Hmmm... come to mention it....) How about
'We don't serve anyone wearing gloves, please remove gloves before paying the cashier'. Justifiable in all shops if you want potential robbers to leave fingerprints, but would in reality lead to little old ladies and children removing their gloves on freezing winters days before they could enter the building. Not what was intended, but no doubt zealously enforced by the
'Im only doing my job' Milgram
experiment mentality.
