I am not surprised that you are ranting after paying about £100 more than expected!
But you have noticed a problem many of us find that whatever we charge its too much for some people.
I quoted £60 to fix an unquantified leak and sent the engineer and he fixed it quickly and only asked for £30 ( in London! ). The customer called a week later saying that something else was leaking but he expected it to be fixed at no extra charge! He is 93 but still goes to see his dentist.
