1 - Person claiming above average inteligence in the automotive industry, when infact they have little inteligence if any at all

2 - Person who changes oil and sells unnecessary services for a living with hopes of making a quick dollar as opposed to keeping a life-long satisfied customer
Ex.1
Technician #1:"Hey did you see that lubie trying to do his brakes over there?"
Technician #2:"Haha yes I did, you know if he would just ask someone for help he wouldn't have to keep taking them apart and re-doing them"

Ex.2
Lubie:"Well mam we did your oil change. we also recomend a transmission flush, coolant flush, power steering flush, and a brake system flush."
Customer:"O that's wonderful i didn't know i could have all that service work done here. Will the brake system flush stop the grinding noise that i hear everytime i step on the brakes?"
Lubie:"Yes mam it will."
(Lubie does services, and customer goes around the block comes back very angry that her brakes still grind. Lubie tells her that it's not their fault she should go somewhere else if she is unhappy, and there is nothing that they could do for her.)

Awesome restaurant cafeteria chain in Texas that predominantly serves old folks, mailmen, and cops delicious, heart clogging, hot, homestyle food. Famous for people who push tea-carts full of iced tea, other refreshments, and condiments. (Unfortunately, the tea-carts have been done away with by new managment which SUCKS!)
I had the Luann platter at Luby's and let me tell you brother, it was off the charts!
