Customer: “I don’t know what happened; the car just stopped while I was driving, and almost caused an accident because of you people!”

Me: “OK, let’s take a look.”

(I couldn’t find any obvious issue, and all the free mechanics were giving the car a full once-over, trying to figure out the problem.)

Customer: “I spent tens of thousands on this car! How the he** can you sell anything that would crap out in 2 days?!”

(Just then I noticed the gas gauge was on ‘Empty’. I put a little gas in the engine and started it up.)

Customer: “What?! For that amount of money, with the technologies these days, you still need to use gas?!”
