Customer service needs a complete over-haul.
I do agree with the Tesco customer on Trust Pilot who said they've never had a pleasant experience in Tesco. I'd add to that view by saying the customer service ethic is awful. I wonder if Tesco are a bad employer to work for as quite a few of the staff seem grumpy and unhelpful and they are not worried about being rude to customers. I won't go in a Tesco store any more.
