Proof of the purchase of goods. There are two distinct types of
- the receipt that sits in your wallet for the best part of a
year before you clean it out, and then pops up again regularly
for the rest of your life, in desk drawers, stuck in books as
bookmarks, or attached to the fridge with a magnet
- the receipt that you think you put safely somewhere, but can't
find when the goods that you bought falls apart/breaks down/
causes you to want to return the goods, for whatever reason....
