Begger inside quick store

I cannot remember an exact date but they was a day last month where i came into the store to buy something and during this time there was a begging that had been in the store before i had even walked in and it seemed as if he was there for a while and once i was paying he was trying to harrass me for money. i have nothing against any beggers i just feel as if they should not be in a store it makes the customer feel very uncomfortable and unsafe.
