Not only because, as mentioned, the check itself is a kind of agreement to transfer funds, and as such the agreement only holds for the amount specified on the check, but also because the additional bookkeeping would be a nightmare, from the bank’s perspective. Not just keeping track of all of it–which check was only partially honored, which check was 100% good–but also, when doling out funds as they appear in the Buyer’s bank account, which gets precedence: bounce fees, or merchandise? IOW, who gets paid first, the Bank or the merchant?
Plus, it turns the bank into Your Mom–“Now, you still owe me $13 from that Pampered Chef party, plus the $25 late fee from the time you bounced that check…”
And then if you get someone with expensive taste and no head for money, who couldn’t keep track of her spending when she was doing it for herself, and if she knows that her Bank will keep track of it for her and pay off the Sellers as she happens to have money in her account, well, that leaves her free to write checks all over town, because it transforms her bank into a sort of Personal Assistant–“Pay the man, darling…” as she strolls out of the store, metaphorically speaking. It turns her checking account into a Visa card.
Banks got no time for that sort of thing.
It’s not. It’s business.
If I sell my 125 gallon aquarium through an ad in the paper, and the guy gives me a $400 check, and I deposit the check in my checking account, and he doesn’t have enough money in his account to cover it, my bank returns his check to me and charges me the $25 processing fee. They can’t return the check to him because he isn’t the one doing business with them–I am, by the fact that I attempted to deposit it into my account with them.
So then it’s up to me to get the $25, plus the $400, from the guy, by whatever means.
And this is why, when you sell something through an ad in the paper, you make the buyer stand there while you take his check over to the phone and call his bank to make sure he’s got the money in his account. Which I did. Heh.
