How to not let a shop damage your clutch

Most reputable shops know not to let the oil change clown ( like my son-in-law ) drive certain cars even if he begs to. LOL
You could disonnect the battery cable and tell them to push it on and off the front end rack. Blame it on screwy shifter linkage or whatever. It wont be the first they've pushed. Then again , if you might get your panties bunched up over some hand prints... nobody will want your business. Good luck
