had a sad experience with these windshield cleaners...went to woqod and filled my tank full. politely asked the guy to clean my windshield. the guy refused because he told me that there are other cars waiting in line.
next in line was a black, window-tinted lexus. the same guy hurriedly took his materials and cleaned the other car's windshield. he just looked at me and gave me a smile...
maybe because i was driving an old mitsubishi lancer that time. lancer vs. lexus....pretty obvious isn't it?
