There are different questions that are 100% inappropriate to ask in different situations. For example, you don’t ask the lady about her age, the rich guy – about making his first million, Tom Brady – about deflated balls… and while on the plane, you don’t ask the cabin crew about anything really suspicious. For example, regarding flight safety.
Otherwise, you – no matter what class you are flying – are almost guaranteed to get increased attention from flight security, and subsequently, even if you were ‘just curious,’ this can cause a lot of inconvenience during further flights. And yet, there are people who clearly ignore common sense – for example, as in today’s story of ours, by the user u/gabe840.
