Trimstab,
Seriously, what a load of old tosh. Smoking is perfectly legal and so I see nothing wrong with this individual buying a packet of cigarettes in uniform. Are you saying that we should not be able to go into a shop on the way home from work and buy a bottle of wine for fear of presenting a negative view on the service. Lets be honest, most of the poor behaviour within the service in the past has been linked to alcohol consumption rather than going out for a quick smoke!!
