Dyslexic D's?

I suspect this is an unintended validation of the name of the Crazy D's truck stop on I-74 at Crawfordsville, Ind.
Or maybe it should be called Stupid D's, or Illiterate D's or Dyslexic D's.
Or was the sign-maker subconsciously thinking of the word "imbicile?"
At any rate, this sign appears on each of the dozen or so gas pumps at the car fueling area.
I made a point of staying with my vehcile while fueling.
