Last night I took an overnight coach back from Newcastle to London. As this coach was stopping at Heathrow and I live only a 20 minute bus ride away I decided to get off there. However as I tried to leave the coach the driver stood in my way and demanded I return to my seat and told me I could be fined if I got off the coach at Heathrow! In the end I told him to either move himself out of the way or get pushed and he relented, but is what he said true? Do National Express have penalty fares and fines?
