Are crew targeted? I don't know but...
My brother was behind a guy who got pulled up by security because he was carrying sunscreen that was labelled 110mL, 10mL over (why a company would produce a 110mL product is beyond me). After a warning, he was allowed to proceed with his sunscreen. My brother had exactly the same sunscreen but this time security said bad luck, I'm confiscating it!
Hang on brother protested, you just let that guy away with, it's exactly the same stuff! "Too bad" was the response..
Right, said brother. Call your manager, there's been a breech of security, you let someone through with 110mL, I saw it!
He promptly got his sunscreen back.
Brother is a Captain, FO was behind him...
