When I was at Uni I worked in the student bar ~ there were loads of wierdos using that place.
A Japanese guy used to come in every friday, order a pizza (They were large, cheap and tasted of cardboard), eat one portion, then wrap the rest in serviettes and put it in his inside coat pocket. I offered him a bag a couple of times (we didn't do take away, so there were no boxes to offer) and he refused it saying the pizza would get contaminated ~ WTF ????
Stranger still was the woman who used to come in, buy a pint of cider and put alka seltzer in it. I thought she was a mature student as she had an SU card and seemed to know some of the other students. The manager, not sure of the physical affect this concoction would have on her, got worried that she would end up ill and one day he refused to serve her. She just shrugged went to walk away and then swung round and chinned him ~ knocked him flat on his ar*e. It turns out she was supposed to be supervised at all times when out in public, but the woman who was her carer sent her into the bar so she could go off to have meetings with her married lover.
