You arrive at your German hotel in the evening and as you enter your room you see your neighbours - man, woman and four year old girl. you smile affably - scaring woman and child if you're me - but get surly response from family. Later that evening you hear the child crying. Then raised male voice and big slap. End of crying. You rise early to find Herman the German having up and downer with black chambermaid. He storms off muttering schwarzer this and schwarzer that under his breath. Obviously in dispute with perfectly charming black chambermaid - male chambermaid that is. Later this same day you return to your room and notice black man furtively putting something back on bathroom shelf before fleeing down corridor in a "what me guv? no guv!" furtive styley. I deduce that Hermann's colgate tomorrow is going to have something of the chamber-boy's ring about it. Here's the thing, he's obviously a cnut. Should I warn him? Or suggest he brushes his teeth immediately?
