Actually I take issue with pilots who don’t stay until the end, or near end, of deplaning. Seems to be a lot more commuters and min rest layovers these days. *sarcasm*
It’s amazing the onboard service you get when you don’t ditch your crew at the first avail opportunity. It pays to show a little solidarity...or just be a decent human being.
I say goodbye every chance I get, unless I’m occupied with work duty or it’s my last commute. Couldn’t care less if the CA or FO wants to bail early. Both pilots share a van to the layover and leaving your own behind will not prevail in any union or CPO.
