In a Swedish-Norwegian comedy movie one of the main characters flying for the first time asks his friend seated next to him how to get some more orange juice. Friend points to the CC call button overhead, thick passenger lifts glass and push button.
Now for the true follow up story.
Two colleagues of mine are on a business trip flying SK and starts talking about said movie and this very scene. One of them, to illustrate, lifts his glass full of red wine straight up into the fully open air vent. Red wine is promptly blown out of glass and rearwards where it gently decorates white sweater of totally pi$$ed of Swede. My two colleagues were laughing for the rest of the trip.
