I must have cheap customers. I've seen guys take twenty minutes to rinse their car with the trigger pulled using just weep water pressure to save a couple of bucks.
Weep Mizer has definitely helped, but when it gets colder and the weeps are on 50% or more, they will still use the wands or the brushes.
Still get the taxis in the middle of the night, I think they have figured out the weeps cycle longer due to the colder temperatures late at night.
Really I can handle the late night taxis, but what really bugs me is lost revenue on those days when you have line ups. Guys tying up bay time rinsing with weep water, or pushing foam around or washing with a brush with time expired.
I gotta admit this WobbleHead idea is very ingenious. Still wonder how it works. I'm assuming it must need a certain amount of pressure and volume from the supply line to work. CoinCW has alluded to that. I am amazed it can firm up enough to allow someone to wash with the brush.
