about a half of a developed country's minimum wage.
FWIW though, I rarely had bad experiences with airport staff. They are just trying to do their jobs in a hectic place and don’t intentionally make our lives difficult.
For the most part I agree most are at least neutral though. I.e. they are there because it's a job, not because they hate people or love people and this job was the way to do that. It's just the ones that do tend to really stand out for people.
