Our local car park has changed its Car park barriers, so now they dispense a yellow chip coin instead of a nice germ free piece of card.
I can see that this may be cheaper for them but every time I go I look over to the other barrier and see drivers put them straight into their mouth in order to complete the whole "window - barrier - quick drive off before the car behind you toots manouvre".
Which, with the card was fine but now I just have a image of these little coins sitting inside the dispenser festering away with the saliva of a thousand strangers all waiting to drop into my hand when I press the big green button.
AIBU or even a bit OCD?
