I would return it. Though, I had a similar situation where I found a $100 bill on the ground in a grocery store. Couldn't find someone nearby who I figured it belong to so I just kept it.
Events like these can make us question our stance on karma and luck.
That is the same way I am, though I do not believe in luck. Karma on the other hand I do believe in. I believe that if you do good upon others, good will come back upon you.
I never take tips, unless they force me to(Believe me it's happened, one little old lady shoved a 5 dollar bill in my pocket when I refused to take it.)
