Disrespectful, ungrateful sales manager

I a customer who was interested in a bakkie that was for sale at Atlantic Auto in Bellville. The manager of the shop never said hallo just got a very angry look from him. I asked him if I could see the roof top tent on the car where after I had to set it up and down in the pouring rain with the manager and his son watching me from inside. After I took the bakkie for a drive I went to the manager to make an offer. There was absolutely no room for negotiation, he **** about the previous time I spoke to him where after he told me I should leave his shop in a very aggressive way. You can nearly say I was thrown out for absolutely no reason. No respect, dishonest, rude, threatening unhelpful are the kind of service you should expect at Atlantic Auto Bellvile
