Having twice witnessed abuse towards a bus driver, sitting alone shouldering responsibility for the safety of both passengers and vehicle, I am sure the reintroduction of the cheerful bus conductors of bygone days would lessen the risk.

They could be recruited from redundant airport staff who have had public contact experience.

This would regain the friendly atmosphere we all used to enjoy and help the unemployment problems at the same time.

Whether human being, animal or bird, it is always "one alone" who is singled out for attack in everyday life.

When are we going to return to ordinary common sense and decency?
