Pet Peaves in Mechanic's Lingo

I work full time at PST but on weekends I still work at a local repair shop.

The one that gets to me the most .............. That is from customers is

"ever since you worked on my car ............." (fill in the blank.) and 99% of the time what they are now complaining about has nothing to do with the last repair that was done.

Just my 2 cents

I get that working on appliances, some times even on one We didn't even touch! (You fixed my washer and now my dryer squeaks. Fix it and I'm not paying for the repair because it's your fault!):wack:
