Tesco are apparently going to change their fast checkout till wordings so that the signs say "up to ten items" as opposed to "10 items or less" because the term "less" should really be replaced by "fewer" as it is an incorrect use of the word "less".
I personally don't care so long as supermarkets actually start enforcing the rules on this till properly.
I've been in Morrisons when a woman turned up with two baskets each with 10 items in and insisted she would pay for each one separately. whilst it is hardly rare to see someone at a till with much more than 10 items.
What is the point of any of the wording in any language if the stores ignore it anyway ?
