You might be asking the wrong question. Most likely Ryko or
PDQ has washed the most for in bay automatics. As also noted, McDonalds has sold the most burgers, but does that mean they make the best ones? For years the oil companies bought the most machines, and the buyers for them did deals in closed
door rooms, or sometimes in the Bahamas. Ryko was actually pretty clever at hiring retired oil execs to be salesmen.
