What! Keepthe money are you mad . What if that was you would you want them to keep it . No that’s what I thoght . Say you lost a wad of money would you want them to get convinced that they needed more stuff. No   you need food and water too . A $100  is a decent amout of money I ment it but if it was me I would want them to give me my money back.So if you say yes you would keep it you are being as selfish as you can be .
