Escalator etiquette

Sir, – Permit me to make a comment on Kevin O'Sullivan's letter (January 20th) regarding standing on escalators by quoting poet WH Davies: "What is this life if full of care, we have not time to stand and stare?"

More seriously, I would suggest we adopt the sign used by London Transport: “Stand on the right”. – Yours, etc,

Sir, – It’s much safer to just stand on the escalator rather than walk or run on it. Take your time and enjoy the journey. – Yours, etc,
