I’m a frequent flyer and I’ve never had an issue with airport staff whatsoever. I always make it a point to be polite and patient wherever, but airport staff are abused beyond belief and being calm will get you 1000x further than if you’re kicking off, being a knob.

Got speaking to a man who worked in security at Manchester Airport and he was telling me he routinely gets shouted at because people can’t comprehend the 100ml rule, don’t pack their liquids properly, blame him because they themselves were late to the airport, drunk people being drunk people, etc... respect honestly because I would definitely not have the patience to deal with it on the daily.
