I had a customer once....said install a backhoe, he was the most demanding guy I've ever dealt with. The backhoe was $7500 MSRP which included installation. But it did not include any fluids that may be needed to finish the install, so I did what I was told...install the hoe, double check everything (including fluid level which was LOW), left a note on the steering wheel to make sure to fill the fluid level in the transmission before operation. Customer wouldn't budge on the price, he wrote the check and that was IT. Dude picked it up, tossed the tag off to the side and proceeded to drive off (no tie downs either). A couple days later it's all over the dealer's facebook page that the dealer forgot to fill the fluid level, I get called into the boss's office and took a chewing, corporate chewed him and myself both out then we had to eat a gallon of fluid. I had to go to the guy's house a couple hours away on my own time and add fluid. Mind you, it's out in the sticks where there wasn't a level piece of ground in sight so getting the level correct in the window was a joke. I left the remainder of the gallon there and got in my car & drove home. Big boss's came in the next day for their normal monthly visit and we all had a 'discussion'--after I showed them pictures of the tag I hung on the steering wheel (with a wire tie mind you), and explanation of the fact that the customer was too cheap to spend $25 on fluid. Didn't matter. "Couldn't you just go get a gallon from parts?"...LOL...yeah sure I'll get right on that. "You aint got any laying around"....nope all out (and the shop really didn't have any). Still didn't matter. I just shook my head and went back to working on something, ignoring them.
