I was there on Wednesday at 9am in the security line with 20 minutes till my boarding closed and I was very doubtful that I would make it in time. I asked the man handling the beginning of the family line or something (medium height, dark hair) if there was anything that could be done because I thought I was genuinely going to miss my flight. He would not let me go in the shorter line, or call anyone for assistance. It was the complete opposite of good customer service. He was completely unwilling to help and seemed very okay with just letting me miss my flight. It's one of the worst interactions I've ever had with an airport employee, any service agent in any industry to be honest, he just did not care at all and it was so shocking and disrespectful. I had a lovely time in Edinburgh but he was one of my final interactions and I'm so so so disapointed. Someone talk to him please, it was so rude.
