Guess I am just old fashioned ~ you offer a service and price your services accordingly. I price my MSK examination higher as it takes longer and hurts my head.
My basic price covers whatever instruments I use and dressings etc. If I supply additional dressings I sometimes charge for them and sometimes not.
I look at it as building client trust and report and no hidden charges.
Bit like asking a bricklayer to build you a wall and he then bills you for use of his shovel, trowel, sweat etc.
I think we could all learn a fair bit about generating income from having a good look at how dentists structure their fees....after a trip to one I never feel bad about anything I charge for...
