The dude sitting 3A CDG-YVR yesterday.
Whilst in the lounge would pick up, inspect bread with his fingers, return to tray and repeat till he found the perfect one.
He was there with wife/partner/concubine. He sat in J (was SE100k), she was in the back somewhere. J had four empty seats. So not only unhygienic, but very cheap and unchivalrous to not spend the money/credits for the one of the four empty J seats, or give up his own.
