Maybe I'm missing the point but what the ...... has role play got to do with being a spark? Mind you there are some good actors out there
Have you ever heard of 'retail theatre'? Shops can charge more by dressing up the experience with comfortable chairs, music, lighting, air conditioning, salesmen giving demonstrations etc.
You can buy the same product much more cheaply online, but the showiness adds value.
There's a Mr Electric video on YouTube somewhere which illustrates this perfectly - the guy turns up in his wrapped van, knocks on the door dressed in his shirt and tie, shows his ID badge, rolls out his welcome mat, puts on his overshoes, unfolds his dust sheet, puts his diagnostic bag on the special tool mat, has a quick butchers, then goes through everything with the customer before actually doing any work.
Without all the fannying around the job could have cost a third of the price, but the customers seem happy to pay for some kind of reassurance instead of having some surly, hairy-arsed meathead turn up in a clapped out old transit and make a mess before demanding a fortune and disappearing never to be seen again. The reality is very few electricians treat their customers like this, but that is the customer's preconception, and that of the career changees who think they can 'gain the edge' with 'superior customer service skills'.
To the uninitiated it seems looking the part and talking the talk is far more important than actually knowing your stuff.
