Capitec atm repair man

I dont have a problem with Capitec bank itself but today I went to Capitec New Market mall and there was a guy there taking pictures of the atm. I was waiting for him to finish. He said I can use the atm. I was careful because these days you cant be to careful. This guy said he was fixing the machines and he was so rude. He said if you dont trust me ask the people imside the bank! He said it more than once to me. I said to him a person cant be to careful these days. I wanted to say to him he musnt be rude to people because he doesnt know what some people are goimg through.
