The one with all the raised eyebrows - very annoying, and what about the guy who when he "gets the call" heaves his laptop off his desk!? He's only going for lunch, he's going to be screwed when he gets back after an hour.
And while I'm here, I have a thing about the Verisure ads - does anyone else detect a veiled hint/subtle threat in the latest one when the woman on the doorstep says to a passing neighbour: "You should get one, Linda!" (subtext - or I'll come round and burgle you when you're out).
