Embarrassing Clients and bad attitude fighting

We are relocating to East London, I went to mentioned store, this guy that was working there just left a heard him call a client to tell her to bring ...back R200 that . He per accidentally gave her.... He came back then finished the client he left there...then he continued... The lady came back with the R200 and he went off on her telling her what cheat she is in front off us all. Then he assisted me gave me a price and thereafter he embarrassed me as well and calling himself a manager... Really so disgusted.... I went to cash converters before greatest service,,,,!!!
