I'm quite blatantly forward when it comes to enquiries, she's heard it a 100 times before even if she doesn't provide extras at least you know where you are every time before getting in the car or booking, the worst that will happen is she says no, job done.
With any booking on the phone I always always confirm girl and services how ever cheeky it sounds, I question extras and costs from the start, as you say it's a waste of time getting there and what your looking for isn't on the menu matey.
