I've recently started taking my own lunch to university in a bid to save money and in the cafeteria there's a machine that gives out boiling water. I used it today to make one of those mug shots and when I went to leave one of the employees (rude at the best of times) screamed at me it costs 20p for hot water.
I was so taken aback and embarrassed that I didn't question it but is it just me that thinks it's totally outrageous to charge for hot water our of a self-service machine? I know 20p isn't a lot of money.
