Sort of lost my temper with the man from Virgin Media who came to upgrade our cable TV boxes. It was bad enough that he had horrible stinky breath and kept calling me "mate". He made me feel like a right idiot, questioning everything I said or told him. Why did we have a router? Why do we have more than one wireless network? When I explained, he didn't understand. He then snatched one of the remotes from me when I opened up the battery compartment to check it. I firmly suggested to him (recoiling from the stench) that he should try not to insult his customers. He even asked for the wireless password at one point, and looked at me in puzzlement when I refused to tell him due to it being a security risk. He may have finally twigged when I asked him for his on-line banking password.
