Drivers represent the customer facing part and image of whichever company they work for. As such they should, at all times, demonstrate a level of customer service commensurate with their company and in which, it is my belief, they are trained in.
They should not therefore come to work and take out their grievances, problems and attitudes on their customers and if that is the case, they shouldn't be doing such a job, or indeed, be employed to do so.
I won't do the job based on just what I say. As I mentioned above I don't have the temprement to cope with the demands faced and the attitudes, from the travelling public, that are frequently demonstrated.
