More of a marketing excercise to get public awareness. Need to make sure your stand rams home exactly who you are. Another good marketing excercise and I've only heard one person do it, is to give a talk to local womens institute groups and the like. Simple presentation such as describing and showing the different carpet constructions, differences in fibres. Fitting issues and how to not let sky and alarm fittings just lift to put cables under. Basic stain removal principles etc. These groups are crying out for things like this. Takes some bottle but make rapport with these people and usually customers for life.
