Mark the inside of your tires with chalk before having them rotated: “LF, RF, LR, RR”
Then after they tell you the work is done, call them liars and let the fun begin!!!
I watch my tires being rotated. But then it’s free anyway since I buy all my tires from the same place.
Many years ago, I took my car to this place called “All Tune and Lube” for an oil change, and they ended up charging me for “replacing a bad spark plug wire” (WTF???)...and they put this blue wire in there that didn’t even match the others, and was way too long...it ended up flopping onto the exhaust manifold and melting...what a bunch of morons.
Needless to say I never went back there, and told everyone I knew to never go there.
I do take special delight in busting fraudsters like that nowadays...it’s great to watch them squirm like the little worms they are.
