You are taking my comment out of context. There was a dialogue between myself and hfly where he was talking about common practices in "fashionable" London restaurants which mean your bill ends up being double what the menu says. These practices bear no relation to reality - e.g. couvert charges, taxes added on top of menu prices and couvert charges, and the blank line on credit card slips. My response was that blank lines on credit card slips were not the norm, since most customers will be presented with a chip and pin machine. The slips can still be offered for foreign visitors who don't have chip and pin, but they are not the common practice.

I suspected from hfly's post that he was being argumentative and hadn't actually been to London. If he had, then I apologise but it makes his posts look all the more bizarre because, as I say, they have no grounding in reality.
