As I idled through the BBC Languages web page today I came across a new phrase - SHOULDER SURFING .
I've never heard of this before - originally it meant stealing someone's wave whilst out surfing but now in American English it has an alternate meaning.
Shoulder Surfing is the act of standing close to someone in a queue at a bank or ATM machine and reading their pin number whilst looking over their shoulder.
Well today I've learn something new..
