Staff at Muller road Bristol are poorly trained and rude- wanted to pay for goods at the self service. Instead, the sales assistant looked into my bags and then demand maned to see receipts. And treated me like a shoplifter- clearly one that wanted to pay for goods at the till. Was made to feel like a criminal. Their online complaints process doesn't work ie doesn't recognise the postcode for the store. Had to send letter in post - still no response.
