The best sales people are those who - on a per-interaction basis - spend as little time as possible working over marks.
It’s called fail-fast. You want to determine as fast as possible if the person you have approached is going to be an easy mark or not. You use a variety of openers and follow-up questions to determine whether you should just wish them well and move on, or actually focus on them to see if they’ll bite.
Honestly, the absolute worst salespeople are those who chase after people who will never bite, and take offence at rejection. Because being immediately rejected is the other person doing all your work for you - they are openly telegraphing that you will waste more time on them than any benefit that will come out of them. Which is why a “f**k off” should always be followed by a “thank you”. Take that as gospel, fail them fast, and move onto the next person.
I don’t know how valid it is these days, but when I was last in Germany in 1989, I asked my much older cousin about automatic vehicles.
Conceptually he knew what they were and that Americans drove them, but aside from large commercial vehicles - and it was rare at the time even there - he had never come across a consumer vehicle with an automatic transmission in his life. Like, everything at the time was stick and three pedals on the floor. Everything. If you wanted an automatic it had to be special-ordered and shipped in at significant expense from America or something like that
