Tesco Improves its English

Tesco is to change the wording of signs on its fast-track checkouts to avoid any linguistic dispute.

The supermarket giant is to replace its current "10 items or less" notices with signs saying "Up to 10 items".

Tesco's move follows uncertainty over whether the current notices should use "fewer" instead of "less"

It's good, of course, that they're finally going to change it to something that is grammatically correct. But what's this "uncertainty" over the current phrase? "10 items or less" is obviously incorrect. There's no uncertainty about that at all.
