Hi, when I was about 7 months pregnant I was caught short. I was in the middle of London desperate for a toilet and I knew if I didn't find one immediately I would wet myself. There was a McDonalds but it was about 200 yards away and I knew I wouldn't make it. So I ran into the nearest cafe and asked if I could use their toilet. They said No! but I said I had to and I was going to use it anyway. He tried to block the way and I was so desperate I said 'you have to let me because it is against the law to stop a pregnant woman using the toilet' (I'm sure I read that somewhere) and barged past him.
When I came out, he had locked me in until I paid some money for a tea or something.
Maybe I was unreasonable but it didn't feel like it at the time.
