Go into McGaggars on a Saturday morning for a juice of the java bean. Just about guaranteed there will be a 16 year old behind the till who will say "Hi" as you step up. My response is to put my hands on my hips and respond in a semi stern manner, "I am not". Usually they get a stunned look on their face. After about 5 seconds of being locked up I ask "did I get you?" Normal response then is a facial change to perplexed and "I am confused". Yup, did not take much. Then just ask for the desired coffee while they chew on the proceding.
