It sucks when your credit card isn't accepted and the machine won't read your coins correctly or missed one and you are thus just 10 cents short of being allowed to use the washroom and now the three people waiting behind you are just like "wtaf is taking so long".

Experienced this a while back in a shopping mall in France. Like, a mall has to be one of the most profitable places in a modern city, pretty sure they can afford to staff a couple washroom staff during business hours while everyone is pouring money into all the mall vendors.
