We clearly live in parallel universes, because I've never seen a
merchant do that (other than for a cordless terminal). And I always take
a close interest in what's going on with C&P transactions.

Admittedly, I don't use a CC in small independent shops very often. But
I did once report an off-licence for grabbing my card and swiping it
behind the counter, as well as asking me to use the PIN pad. (The CC
company issued me a new card immediately, and the shop went out of
business about a year later).
