The Next Web says Tesco is rolling out a free Wi-Fi service in its UK Tesco Extra stores, powered by O2. The chain offered a statement:

So far, customers have been using it to read product reviews and compare prices while they shop.

This being the same Tesco which argued with a Guardian journalist writing down prices in September:

You’re not allowed to do that. It’s illegal. […] It’s illegal to write things down and you can’t take any photographs, either. If you want to check the prices, take the item to the till and pay for it there. The price will be on the receipt.

A manager clarified the latter point:

Look, it’s company policy, you’re not allowed to do it

So: left hand/right hand, change of heart, Tesco Extra only, or Tesco oddly saying “well, you can use an iPhone to check prices, obviously, but if you write anything down, we’ll kick your face off?
