I don't know how much flight attendants make, but whatever it is, it should be doubled. They deal with terrible behavior from passengers (remember that guy who tried to open the door mid-flight?) delays that they aren't paid for, and unpredictable schedules. They're the unsung heroes of the sky, and they get very little appreciation. Everybody loves to thank the pilot at the end of the flight (some extra people even clap), which is fine and dandy, but the same should apply to the service crew. They're managing to not spill ginger ale on everyone during turbulence, dealing with somebody's drunk uncle, and maintaining everyone's safety, all while smiling.
I always try to be nice to flight attendants, mainly because it's the right thing to do, but also because they might give me an extra Biscoff cookie. I love those things. So if you're a steward of the sky, take these memes as a token of our appreciation. Sincerely, your passengers.
