Bad service Debonairs Pizza

Today I received a poor customer service from Debonairs Pizza Randburg Manager Mr Joseph.I came in the store with a drink and placed my order.I opened my drink while I was drinking Mr Joseph came to me and said I must wear a mask.

I explained to him that I am sitting alone there is a social distance between and other customers.I ask him that What going be different when I eat pizza and drink .He failed to answer me. I'm very disappointed because I work around it was very convenient for me to go and chill there while I grab something to eat
