Sorry HotSexyBBW, charging people to enquire about services or make a booking IS WRONG.
Having been in business for many years myself, I've learned to accept timewasters, dreamers, people who want to argue on prices and people who shop around everywhere are just a normal part of being in business (whatever the industry). You should accept it too. No matter how good you are you will never turn every enquiry into a sale. But charging people to make an enquiry is like a tradie charging people to give them a quote.
What worries me (as a customer) is that if we don't all resist this sort of thing, it will sneak in and before we know it every WL in perth will have a 19.. number and be charging us to make our enquiries.
My 2 cents.
