Me. Because I thought my camera was broken and that the flash had died, so I drove 40mins (1 hour round trip) to find out that someone (not me) had accidentally turned off the flash setting. As in, the lady at the repair place took wee camera to the fixing-up blokes, who turned it on and solved the problem in <2 seconds.
Ouchy embarrassed me. On the plus side though, there is $55 I don't have to pay!
