The doordash deal is even better than the double burger layaway program in Good Will Hunting:
Your sandwich? I paid for it… give me the $0.16 you have on you and we’ll put your burger in layaway… we’ll put you on a program… every day you give me $0.06 and at the end of the week you’ll get your sandwich.
I worked in the grocery stores back then. People who got paid on Friday would come shopping the Tuesday before and write a check knowing that the check wouldn’t make it through the system until the following Monday. As long as they deposited their check on Friday (which would post on Monday), they were fine as the deposits were posted first and the debits came out second. This was normal before the electronic clearing houses. When the electronic clearing houses came into being, a lot of people got hit with overdraft fees and/or bounce check fees until they learned that life had changed and now had new rules to play by.
Not sure what the age requirement is, but I’m pretty sure if you can remember using 1200 baud or slower modems, you’re good to go. Loading programs from a cassette tape is also a good thing to know.
Of course, some of us remember using punch cards, and not just in school…
