I deal with scheduled and loco and can confirm that loco pax are a different breed. Everytime I'm dealing with the loco I end up being shouted at for something that is not my fault, ie late pax, is that 60kgs of baggae you've got with you? But it doesn't happen when dealing with scheduled, there is the occasional disagreement, but at least you can have a coherant conversation with scheduled pax.
I don't have the patience of a saint, but I do have high blood pressure
