Danes visiting UK. We used train line a few times and it went really well the first few times when buying the tickets at the station, however, we had to get up early to get to the airport so our friends suggestes buying them online the day before. Unfortunately none of our cards worked for this so our friend bought the tickets online and sent them in an email. Turns out that you cannot open them using an android as it was purchased using an iPhone.... This was fine for the controllers as we also had pictures and I guess they could see we were the first scanning them. But some lady at the airport just got so mad and kept telling us how stupid we were for doing that which was such a terrible situation to be in. We told her we were fine with paying the tickets again or a fine but she just kept going at us... By the end I told my girlfriend that we should leave and find someone else. Luckily we found an older man named Nick at the Manchester Airport who helped us pay and he just told us we were being way too nice in this situation. 0 stars for the first Lady but Nick was such a good guy and more people could learn from the smile he puts on others faces
