Tuck this in there somewhere near the end
Early 2000's a manufacturer of professional lighting products puts several service vans in the southwest on the road wrapped with fancy graphics and company logos.
They start offering free nighttime site demos to prospects of contractors who are presumably too lazy to do them themselves.
In addition they offer service and repair on those systems that contain 100% of their product coddling and supporting the contractor who will not care enough to service his own system.
This spawns a frenzy of other manufacturers to follow suit and assist with the sale of their products via free Nighttime site demos and even assistance from sales reps on the first few project installations.
Rumor has it that they would even follow the contractor into the port a John holding a roll of toilet paper but that rumor was never substantiated.
