I read a story of a (non-Jewish) wedding at some vacation-spot hotel, where the hotel supplied the photographer, and lost all the images before printing any. So the couple were left with no photographs. (And sued the hotel for tens of thousands of dollars.)
I also know someone close (frum) who hired a photographer that was also supposed to do the video. But the video guy booked the wrong date, so there was no video. (But the photography was good.)
