Madam, - Shane O'Sullivan (Dec 27th) expresses severe criticism of the refund system used by Dublin Bus, without as much as a hint of a suggestion for an alternative. One can only assume that Mr O'Sullivan is too young to remember the robberies, beatings, muggings and resulting trauma suffered by bus workers when they were handling cash. - Yours, etc,
MATTIE LENNON, Lacken, Blessington, Co Wicklow.
