Franchisee lost his temper!

Today my fiance and I got up and went to the counter to pay for our meal, we wanted to pay buy card... The transaction went through the first time as we got a notification by sms, the franchisee told us he does not think it went through, he wants to try it another time, the transaction went through a second time. When my fiance asked him about the first amount that went off on my fiance s account he got very angry and told us he is not *****ing our money, he ensured us he knows what he is doing and will give us R500.00 if he was wrong, he then said he knew the amount only went off once and our sms confirmation was wrong there for he is not wrong. My fiance spoke very calm and asked if the money is going to be reversed, he did not answer him so I repeated the question, he slammed his hand mm away from me onto the counter and started shouting he knows what he is doing. We were very unhappy and he told my fiance not to look at him as is old enough to be my fiances father, my fiance took my hand and we left as the franchisee came across very aggressive. As we left he shouted that he thinks we should come back and apologise to him.
