I work behind the scenes for a garage, so I don't personally see things, but I hear stuff.
Like yesterday some lady at one of our garages was complaining because she had originally been quoted for blown heads & gaskets, but upon tearing the engine apart our mechanics found that her water pump was done for, 9 hoses were "disintegrated"
, and both coil packs were shot.
When asked if she'd like the extra work done, she agreed, then later complained thinking all the waterpump/hoses/coilpacks were free...
A buddy of mine at Midas has some interesting stories.
Opens up oil pan, finds mysterious chain link. Still ran.
Customer complains about weird noise and rancid smell. Rat climbed up a chute and was decapitated by this fan.
Completely different customer, this one was today. ENTIRE RAT'S NEST. WTF.
