Consider an exmaple where Officer A visits a family member who happens to be Rating B over XMAS. Does Officer A have to make his excuses and says sorry Dad/Brother/Sister I cannot stay with you for fear that if we have an argument after a few too many beers, then I will be punished for being a poor officer and for that matter you will be too?

2. If it did, then Officer A minds his tongue, slows his drinking and if it comes to it, has a scrap out of view of CCTV and the public at large
