you only have to compare the shopping experience in its stores with that of its rivals. There's no comparison!
What? Are you saying that a trip to Asda is an uplifting experience?
Most of the branches of all the big supermarkets that I've visited are much the same, and whether the experience is pleasant or not is far more a product of the area where they are situated than the brand.
Tesco stores are dreary, cheap, shabby, and uninviting. The product offer is nothing special. The staff are mostly low grade, and the customers on benefits.
This is an absurd generalisation, and I think it says rather more about the area where you live / shop than Tesco generally.
If they are as bad as you say why do so many millions of people continue to shop there? And there are 15 million Clubcard holders - I hadn't realised that you received one as a reward for signing on.
As you started in retailing in 1959 were you by any chance driven out of business by Tesco? Your comments sound like those of a bitter person, driven by prejudice rather than a rational assessment.
