In the mid 00's I had a digital agency and we hosted sites for a few fairly large hotel chains. One day, I got an email from procurement at one of them that said, "we're holding payment on all outstanding payables until next month." The hosting billing system shut their site down at 12:00pm the day after payment was due and dutifully redirected to the "pay your bill online page". Ten minutes later I get a frantic call from procurement, begging me to put the site up. I fumbled with the billing system, and finally told her, I think the only way to fix it is make a payment... which she did. $6,200 on credit card. The customer never missed a payment after that.
