No I drink and wife is happy to drive on the very rare ocassions that we visit a pub, cant afford it very often, but the same in a restaurant where she asks for a glass of tap water.
I never drink and drive even 1 alcoholic drink. That is not to say I havent in my younger days and been very lucky to not get done but as they say I saw the light.
He would have thought no doubt that the police would have expected that his friend would have phoned somebody who hadnt been drinking so the chances of getting tested even with many police about was very low.
