A foreign ( literally, different country ) pilot flying a Mooney aircraft read the aerodrome instructions for my home airfield, left hand circuits, but then did a right hand circuit and nearly collected a Turbulent - me - letting down on the 'dead' side. Why ?
The pilot heard one of our 'locals' saving time by joining straight in from a right base, and thought we must have changed the circuit direction.
Reading the manual isn't always infallible - eyes and ears open pls. You canna be tooo carrrreful.
