Client wanted a site for the 100th anniversary of an important local musician. They wanted to show calendar of events, biography, store, and more. We started the work 8 months before the commemorative date, and after 4 months, the site was 99% complete and waiting final review and approvement. 2 weeks of silence has passed, when I got an email saying their deleted the site from server and all backups, and now they wanted all the work back.

With luck, I could restore a partial backup, and the client didn't want to pay for redo the rest of the work.

10 months later (yes, after all the events has started and the site being off) they contact me again, asking to continue the work.

I was happy to say no.
