Billed for broken item while shopping at Decofurn in Boksburg

I went for shopping on Saturday the 30th of June 2018 at Decofurn in Boksburg with my partner. We were walking pass the Vase, I accidentally hit it with the handbag when it fell and broke into pieces. The shop manager insisted that we pay the full price as it is his shop's policy that their client's pay for any items they break in the shop.

I was in dispute based on my understanding of the customer rights however, the shop manager insisted we pay for the broken item. My partner and I did mention to him that its a first we hear of this ruling as other shops never charge for broken items prior purchase. The manager went on and said its because "You" guys always run away when you break things.

We ended paying for a broken vase!

Help advise on this matter, I am very concerned as a customer and the practice of the principle for consumer rights in this instance.

The manager's name is Jag Werwey.
