My hire van story... my brother's band was playing (in Scotland) for my other brother's partner's 60th.
First Bro drove van full of gear up to Scotland. Rest of band flew into Edinburgh. Second bro hired a Sprinter minibus, set off with him to collect band and some other folks, on way beck we went to Coop in Dunblane for 'essentials'=huge quantity of alcohol. On return to minibus sliding door appeared warped and wouldn't shut, so I gave it a more enthusiastic shove. This time it shut and the glass cracked - not a sudden shatter but a progressive breaking into ever smaller shards over a couple of seconds. Looked very impressive!
We patched it up with parcel tape and the next day the hire company agreed the door was at fault, swapped it for another (lesser but actually nicer to drive) minibus and all was fine.
Ever since I treat sliding doors very carefully.
