Some folk are just so thick. The local carwash offers tyre/engine clean, low-pressure prewash, high-pressure soap, suds brush, foaming conditioner/polish, high-pressure hot wax, high-pressure rinse & low-pressure mist rinse. The foaming conditioner is supposed to go on painted surfaces only after wash & rinse processes.
So this daft woman enters the wash bay in a clean dry car & proceeds to spray the foaming conditioner on every surface without dampening them. Glass, paint, plastic, all done. Then she grabs the suds brush (with no soap running through it) and spreads the foamy polish with the slightly damp brush. Hello scratched paintwork, dopey!
Each cleaning feature has words & pictures of the processes on a big placard beside the control panel. No excuses for not knowing how to use them. But this daft cow goes in and essentially deliberately scratches her paintwork thru ignorance.
I stopped watching at this point as another bay had become free for me to give my dusty car a quick clean.
