[This is DA BEST!!!!] I'm at Da Bone this morning, and a guy comes in for some wiper blades for his work van. OK, no prob. Then he axes for something to clean his windshield. OK, again no problem. I take him over to the cleaners. He then says he needs something "very strong." BECAUSE....he "accidently" had some kind of acid stored in a wiper fluid type bottle, he added it to the washer fluid tank in his van, then when he hit the washer spray button the acid sprayed all over his windshield, etching it VERY badly! I just said "ummm, ahhh, ohhh...." and burst out laughing in his face. Needless to say, he got pizzed...but OH, WELL!!!
Anywho, I calmed down and told him his only bet was a new windshield, and to be careful how he stores his chemicals.
