It's not just the legality of it, it's similar to what we've discussed in the past, with relation to the service provided on Facebook. Why as a customer should you receive a different level of service depending on which day you wish to use it?
I'm surprised someone hasn't said it yet, but I'll pre-empt and answer the question anyway. It would be a different matter if a different vehicle has to be used due to break down, but lets remember that this is an operational decision, i.e. one within management's influence.
