Now a store that also does the mail like was described. That is was a shop but they also had mail boxes and gave people their mail, mailed letters and sold stamps etc. This was a gray area. If he/she uses the same counter for sales as he/she does for PO business? This I am not sure about. Is the whole store PO Property? Just the part used for Mail? IF you are buying something from the PO then I would think it would fall under PO Regulations. But if you are buying some trinkets from the store but use the same counter would that be the PO then? That is what I am not sure about.
