Rudest manager Milton The glen Checkers

I saw a post on stock pile SA of the Air fryer going for R999. I went too The Glen shopping centre Checkers. Met a very nice and helpful sales lady who took my phone to go find out where the special is she came back and said the manager will meet us at the isle. We went there and the manager Milton started screaming at the sales lady about the price I said to him there is no reason to be screaming at staff like this , he turned to me and was very rude and said the price is R1999 that's his price and turned around and walked away when I asked the sales lady for his name he turned around and yelled at me Milton. This is unacceptable behavior from a manager to treat staff that way nevermind customers. He should not be working in retail or be a manager i have never in my life met someone that is this rude.
