We should bring in a service charge just like the energy suppliers or phone companies do.
So a £15 job would be £10 service charge and £5 for cleaning, that way if the customer decides they don't want them doing for whatever reason they still have to pay the service charge.
just like if you're not at home for whatever reason and you're not using the leccy you'll still get a bill for having the power provided to you, whether you use it or not!
When I get this response from a customer I usually say that if I let them have a space on the round they need to use it every month, if they don't , that empty space costs me money and I will have to take someone from my waiting list to fill it.
So basically I expect them to commit to the service if I am to commit to providing it for them.
Its a two way thing.
