Ok, now I like to take pride in being a good person (despite some of the sick, twisted shyte you may read on here), and yesterday something happened. In the past, (and I'm sure this has happened to a few of us) I have gone to Coles and used the self checkout and found some change that hasn't been collected at the unit that was used. I have always picked up the coins and given them to the team member there. Now I don't know what they do with it, hold it for a certain time if someone comes back asking for it, or put it back in the machine, or steal it themselves, but that's something I've done. Now yesterday, I went to use a unit, and waited for the person in front of me to finish. I went up, scanned my 3 items, and put my cash in. I selected no receipt, and then waited for my change to come out. As I did so, I saw a $20 note sitting there in the dispenser. I thought... this can't be mine, I only put $5 in... and my change came out. So I picked up my change and the $20. I remembered what the lady in front of me looked like so I walked outside hoping to find her in the car park... but she wasn't there. There wasn't even anyone loading/unloading things into their car. I walked back onto the street and couldn't see her anywhere. I walked around the block to see if she was parked on the street or used the alternate entry into the car park... no luck. What I was going to do was ask her if she could show me the receipt from her purchase to see if the $20 change she should've had was correct. I simply would've told her that some money was left unattended and if her receipt adds up I would've given it to her. I couldn't see her anywhere however I really wanted to give her the $20 back - it would've been a good deed. I didn't hand it back to the shop either because technically, it wasn't their money, it was hers (most likely). Did I commit a crime? If so, how?
