My wife feels the same way about Tesco fruit and veg (it's one of the first things she commented on when she moved to the U.K.), and she's not English.
Tyrell's crisps taste like very good home-made ones. Pringles, to me, taste like the factory produced potato things that they are.
I'm not saying that it's wrong to like Pringles but they are not in the same category as Tyrell's crisps (and probably appeal to a different market).
Lots of people like the taste of the fruit and vegetables here much more than that at Tesco even if it goes off quicker.
I understand that to you - how long something lasts is more important than taste. Well, you're luck is in - they still sell tinned vegetables, originally developed to preserve food for military campaigns back in 1800.
But, if you said that fillet steak was rubbish as it went off after a few days where as a burger king burger could last until next century, and hence was a better choice, I would think you were a bit odd.
I just want to take this opportunity to thank you for standing up for the many who demand white bread riddled with preservatives, fruit covered in wax and pesticides, burgers that are more ammonia/antibiotics/hormones than meat, and god knows what other mechanically separated unidentifiables you gleefully stuff down your gullet.
I thank you for your view and please note that I wasn't as pathetic as you as to groan you for your view. And whilst I am at it I thank you for proving that I am right, You pathetic little people who tell us what we can and can't eat are a rea lpain in the arse!
