Uncomfortable eating inside and drive through

While my wife and myself was eating at KFC Langenhoven Park today when two beggars came inside of the shop and started digging into the trash cans besides our table. My wife told them to leave, the refused and i was force to remove them physically whilst the staff inside the shop did nothing. When i left the shop they waited for me outside with another bigger gentlemen. When i went to my car he began to swear at me and was aggressive, I reacted and almost got into a big fight with him outside of your shop. This is not acceptable and makes me not want to go back to your shop again. I must add that this is the second time that i have had to get physical with the beggars outside of this shop as the staff does not do anything regarding the beggar problem. They have hindered me on the drive through as well every time i have gone there.
