It sounds like exactly the sort of think that you were wanting to know, but it’s not likely to be something you can easily find out about. So bang, now you know your character should have the habit of sniffing open drink containers, and you don’t have to explain why until the end.
There is truly no substitute for finding someone to ask.
There’s a bit of a leeway in there, I think. When “examining” stuff, people don’t really expect the result of a proper examination, just the same as “look at thing”.
But there are words which are part of one’s vocabulary and life which may not necessarily reflect their literal meaning. Easiest example, I am atheist but I still say “Oh my God” and “Jesus Christ” when shocked. It’s cultural.
