I got off the bus in a near-coma once, when I was going to school (full-time school and full-time work will do that to you) and left my entire knife set on the bus. It didn't show up at the lost and found, so I was really in tough at class for a couple of days.
An acquaintance who was a corporate chef and seldom cooked any more stepped up and loaned me his spare roll as a stopgap, and fortunately I qualified for a special program administered by the school (call it the "Oh Crap! Fellowship") which paid for my replacement set. Here in Canada, at least at the schools I attended, it's mandatory to purchase a ridiculously complete kit before classes start.
