Most of the problem with finding customers is that all of the effort is
in preparation. Any fool can plaster a simple wall. Consider the
problems of stair wells and old houses, nitches and alcoves, property
where the occupier is a pain in the arse and poor payers.

One I heard of -- customer's kids running around house, tread wet plaster
into all the carpets, and then you get sued for recarpeting the house.
