Flight had been cancelled the day before, had to pay an additional £50. No empathy shown, just told I could claim it back from the airline. Machine didn't provide receipt, when I asked for one the guy on the desk told me I didn't need one as it was printed on the ticket. Explained it just showed I had paid £50 not that this was an additional £50 on top of the original charge. After he huffed and puffed a little he begrudgingly said he would have to give me a hand written receipt, to be honest this didn't really explain that it was an additional charge but after travelling for 2 days I'd had enough and just took it and went home.
