Back story: I work as a bartender at a bar that is right after you exit security at International Arrivals at an airport.
Had several customers sitting at the bar, and we were all talking about how Lufthansa pilots are going on strike, and there's been a lot of cancelled plans/major delays in the last few days.
Customer: I don't know what's going on! Must be something in the air.
Me: You mean there's nothing in the air.
Cue entire bar groaning. Got a few good tips out of it.
