I take your point, but more than just the customers loving it, I would love it.
I did two house inside today, and because of the sun, they were more or less dry. They were perfect. It's not the result, its the fact of leaving them dry I like. And to be honest, some people don't do wfp properly and people dump them, hence comments from some like 'there's loads of work to be had from people who don't like wfp'. This would totally eliminate that. Besides, it seems to be the natural progression.
