Home Centre — unjustified billing

I have regular customer of home shop since last many years, in my last visit dt 22.06.2019, i was looking for dinner set and while walking around, a dinner plate by chance touched my bag, fell & broke, i was not even holding that plate. But store manager, but store manager asked me to pay for plate and when i told him it that i was not even touching that plate, then he argued to pay for it, which i does. I did pay for plate approx rs 450 but that was unjustifies
