Cancellation of Booking with no Questions Asked

I travelled to both Durban and Cape Town earlier this week for business. On both occasions a colleague had also travelled, albeit on separate flights. Having our respective PAs handle our bookings resulted in us booking two car hire vehicles when in fact we only required one. On both occasions I asked Europcar to cancel my booking which they agreed to do without argument, question or fee! Where in today's world does any service provider neither argue nor levy a penalty for a booking not fulfilled?

Europcar - you are truly a pleasure to deal with!
