Rude manager.

I went ti Chris hani pick n pay the manager there was rude to me when i asked for help and had to go on and shout an employee which i find it to be very wrong to do in front of cuatomers. Nevermind he could not help me and was just moody for someone who works daily with customers to scold an employee in front of the customers is just wrong in many levels. Where is the respect to the fellow colleagues and us the customers.
