Finding an item in a well-traveled area

Hi,

One who finds money in a store, in the consumer-traveled portion, may keep it - it may be presumed that the person who lost the money does not expect to get it back.

If one finds it in the propietor area, though (such as behind the counter), one must return it to the store owner.

(Code of Jewish Law Choshen Mishpat 260:5)

Have a great day,
Mordechai
