Fine Summer afternoon, old car needed gas before venturing out to run a few errands. Take it down to the local gas-bar, this one has both self & full serve lanes. Spy a new kid working the full serve & can't resist. Park it, shut it off & roll the window down. "Yes sir, can I help you ?" "Fill 'er up hi-test, please." Kid walks around the back & ventures over to the side closest the pump. You can see the look on his face when he realized the old fart driving this old time tin put it on the wrong side. He comes around with a look of satisfaction, just like the cat who ate the hummingbird. Ready to ask the the old guy to move it around the other side & thinking to himself " Geez, hope I'm in not that bad when I get to his age". Right at the LH quarter he notices no gas cap on that side either ! Goes back to the RH side to double check, returns again to the LH side. Genuine confusion has erased the smirk of a few moments ago ! No, he doesn't want to ask the old fart driver. Yesterday he got the job only after convincing the Owner he was a B student with a mind for auto-mechanic training later on & he's certain he knows everything there is to know about putting gas in a car. Goes inside to ask the cashier about these old cars, she doesn't know either !"You're working gas today, figure it out" .After a couple more minutes I get out , wave him over & show him how it's done. Second time, 2-3 weeks later he knew just what to do.
