Yeah. And if you do happen to enter you PIN, request cash then just walk away, the machine will furiously beep for a short time then pull the card back in ("swallow the card"). You've then got to request a replacement card from your issuer but it does limit the chance of a stranger coming along and retrieving the forgotten card and attempting to use it (for a signature fall-back transaction after damaging the chip, or for a cardholder not present - CNP - transaction). Bank-operated ATMs will also often retain the card if it's been reported lost or stolen, but this does rob the lucky/brave checkout operator of their £50 bonus if they happen to retain a stolen card that's been used in store.
