And it wasn't just the general public....
Back in the day when I was a newly branded B727 f/o, I flew a trip to MCI or ICT (can't remember exactly). What I do remember is my entire crew being under the age of 30. The Capt was 29 and the engineer and myself were mid 20's.
After arriving at our destination early one morning we were picked up by the hotel van. There was already a red-eye Braniff 2 crew on the van (2 pilots and 3 FA's). After exchanging a few pleasantries we took our seat. One of the female FA's looked to be in her late 40's-early 50's. After a short period of time she spoke up and started asking my Capt questions.
Her: UPS has airplanes?
Capt: Yep, 727's, 757's, DC8's and 747's.
Her: What did y'all fly in?
Capt: 727
Her: Ya'll look kinda young to be flying that! My boyfriend is working on his Private pilot's license...did ya'll have to have a multi-engine rating to get on with UPS?
(Now, keep in mind I'm sitting right next to her Capt who is now turned away, looking out his side window and quietly tearing up and chuckling as I can see from the reflection in his window).
Capt: (Now in a deep eastern Kentucky Jethro Bodine country draw..). Wa heeell, no! I still don't have one of them there "multi-engine aeroplane ratings" cause every time they failed an engine on me that ole’ thing just rolled over on it's back and we'd crash and get ole’ kill'ed...or worse! I'm gonna try again and get one of those I-F-R cloud ratings first and then take my test for my multi engine aeroplane ratings! When I get'em all I'm gonna go fly for an real airline!
(At this point her Capt just busted up laughing, looked at my Capt and apologized profusely for her noob questions. We all thought it was pretty funny and got a good laugh but that mentality is still alive and well even today.
BTW...as we walked into the hotel I remember her Capt asking us where he could send in his Resume.
