Boing-boing-boing....
Here is a little fact for you primitives --
Q. How many major corporations actually read your checks when you pay them ?
A. Almost none. Because of the sheer volume of mail received, check payments are read and processed electronically, save for what few are deemed illegible by the electronic reader, which are then siphoned off to be processed manually. These machines open the envelope, retrieve the contents, read the routing number info on the check and the amount its made out for. the information is then bounced off your bank, and if the funds are there, the bill is paid.
Notice I didn't write that the machine reads who the check is made out to.. If you make the mistake of sending the payment for your water bill to your phone company, the phone company will cash that check and apply it against your bill.
So, nobody read your little note, and if they did, it was long after it was separated from your bill, once it ended up in the reject pile.
