Throwing my items around

Received such rude service last week. Every time my item was scanned, the teller THREW it to the side. This caused all my breakfast bars to be broken and messy, The crisps were crumbly, my cold drink overflowed due to gas build-up, the biscuits i bought were broken. I pay and I pay for quality products. I don't expect them to be thrown around once scanned. I would definitely think twice before going there again!
