90's kid here. I once used an auto-pay system where the $5 charge for "convenience" went through, but the actual payment didn't. It didn't even attempt to notify me about the failed payment, and I had more than enough money in the account. Bank didn't even have a record of the payment being attempted. I got hit with $300 in late fees.

Since then, I pull out an honest to God typewriter and type up a check. I cackle with glee at every key I push with full force, knowing full well a human being has to be paid to physically open the envelope, read the paper, and retype the information into a computer. Plus, I get to support the Post Office.
