How would you feel about this?

That is why you never let your mind wander as it can cause you to forget what you are doing. people are not as honest as they used to be but you could go to the owner of the place and tell him you left $ 100.00 in the ATM someone might have turned it in there is hope that someone would be honest instead of saying finders keepers. Thanks for the question.

I would feel stupid for losing $100 that way.  

I'd feel terrible. So much for Good Samaritan's.

I'd feel like an massive idiot to forget something so quickly.

It's only money, I can always get more.

I’d feel mighty stupid

That would suck. I would call the bank in the off chance that someone turned it in. It happens. And of course I'd try to be more careful in the future.

I would have told the man that I left my money in the machine before any of that transpired. He would have closed the line and taken my money out for me.
