I hope to god I don't ever accidentally drop a £20 note in front of most of you lot in the hope you may pick it up and tell me rather than keep it and smugly claim it's morally yours.
What a bunch of self centred and entitled people in this thread.
Well as there is an as yet unstated cut off point before moral bankruptcy hopefully you'll drop a big enough wedge to tip the balance of the scales of common courtesy back in your favour.
Talking of karma, it does seem to work.
I was on my way home from a 12hr night shift a few years ago and had to stop off at a cash machine. Popped in the card, punched in the PIN, selected £100 and started thinking about my bed while the ATM did its thing. Out came my card which I slid back into the cardholder before turning and walking back to my car. I hadn't got far when the woman that had been waiting behind me shouted "Hey mate, don't you want your money?"

Payback perhaps for all the times I haven't taken advantage of other peoples mistakes? Thank god it wasn't Brandane behind me, he would probably have trousered the cash and thought he was doing me a favour by teaching me a lesson for being such a dozy sod!
