Depends what it is...
Once an old man who was very poor-sighted asked me to help him at a cash machine (ATM)
He asked me to assist him to withdraw some money but what he didn't realise was he'd already drew out £300 and it was sitting in the tray ready for him to take.
I guided his hand to it and helped him put it away in his wallet.
That was the right thing to do.
Another time a lady pushed in front of me in the ATM queue, was huffing, puffing, cussing etc.
She tapped a load of buttons then stormed of. As I approached, £300 came out so I swiped it.
Do I feel guilty? No she was a cow!
I'm sorry but the last few paragraphs just made me laugh out very very loud!
To be honest I don't know what camp I'm on here. I'm probably mostly like Ms Williams in that I assess every situation as it comes.
One of my clients last week gave me a big holdall of waxing products (she used to have a salon and had had it in storage). Vitually new 1000 wax pot, phd and hive roller system. My husband questioned me when he got home (thought I'd been a a spending spree!) as the stuff was still sitting in the hallway. He said to me what would you do if you found £500 cash in that bag. Well on this occasion the answer was easy, I said I would give it back (well actually I said I'd give it back next week cause we'd just got back from hols and were a bit short Lol but I'd defo have given it to her).
