My short stay in Bahrain was immensely improved by this incident which I witnessed from the hotel coffee lounge on the mezzanine level, overlooking the lobby. Whilst one group of Japanese tourists filed out through the magnificent plate-glass revolving door another group started filing in. For Japanese people to fail to bow to each other is unthinkable and so they did; the sound of foreheads hitting glass was like a crate of apples being poured onto a wooden floor. The door was jammed with concussed Japanese and the lobby was littered with others stumbling and falling, unable to avoid crashing into the people ahead when the line abruptly halted. Some guests thought it a terrorist attack and screamed and ran for cover. O Joy.
