What do you think is fair?

It happened to me a few times that some people,after they make an appointment of one hour,they pay for it,everything is ok,but after half hour they just say if is ok for them to switch the appointment for half hour.After the half hour they are happy,they don't complain about service but they just say they are in hurry or they find another excuse.In this situation i always returned the money for the other half hour,but it drives me mad.
On one hand i see it fair enough to give half of the money back,if the guy only was with me for half hour,but on the other hand,when i make an appointment of one hour,i never double book and i can loose another booking,so my time and my money are wasted.From the customer point of view,this is fair,but from the girl point of view is not!What do you think about that?

They book an hour and if halfway through they change their mind and leave after half an hour, then it's their loss, you allocated an hour, so I don't see why you should be out of pocket, fuck them Jessica. Ryanair wouldn't give you a refund if you booked Abu Dhabi and then decided to get off in Paris.
