Confession
Definitely a story that made me smile, but I have a confession to make (different technology, different circumstances, but much more recent):
At a self service checkout (I hate those things and avoid to use them whenever I can) I put a £10 note in the slot where people put their discarded receipts, rather than the 'money in' slot. Needless to say, the machine didn't accept the payment and I had to get an assistant to retrieve the money...
Anonymous Coward for obvious reasons...
