I have actively boycotted Tesco for over three years, and can't see that changing.
We have an Express store 200 yards from our house that I refuse to use, ( I go to the independent shop next door instead, he's cheaper and friendlier) and another NINE branches within a seven mile radius, including two Extras literally within a mile of each other -either side of a reasonably large housing estate, walking distance apart.
I live in an area of roughly 100,000 people - we now have more branches of Tesco than we have secondary schools.
I have several good reasons for avoiding them - I don't like their business practice of putting a shop on any available site, as to me they are disguising greed with convenience.
At least three of these "Express" shops have been built with no parking provision at all, meaning people constantly park on double yellow lines, across junctions and even on zebra crossings just to buy a pint of milk - yet when my OH was in there once getting some stuff for work (he still goes occasionally but I never do), the manager was literally shouting at customers for blocking her delivery bay. He had walked there, much to her annoyance.
The little shops are consistently much more expensive than the bigger branches, but if asked why, the staff say they are a separate company and have nothing to do with the main Tesco (WTF?!)
I lost count of how many simple requests were met with rude or arrogant replies - for example, "Do you have any frozen sweetcorn, as there's none out?" Reply: "Well, does it look like it?" - that happened on several occasions in two branches and was the last straw.
And they are too expensive as well.
Luckily I live within driving distance of all the other supermarkets, ASDA, Sainsbury's, Morrisons, Aldi, Lidl, M&S and Waitrose, and both ASDA and Sainsbury's are opposite Tesco so there is plenty of choice, and no-one has to go there if they don't need to, but I would hate to be forced to shop there.
The only regret is that lots of my mates get great Clubcard rewards like theme park tickets, but I refuse to give up my principles for that, so I can't claim them!
I'm not for a second saying all Tesco staff are rude, of course they're not but I have met plenty who are - it's almost as if being the number one supermarket gives some of them a superiority complex that I refuse to buy into.
Sorry if you work there but are lovely!
