Devil's advocate, what if the owner broke something, or is chasing a noise or phenomena that is hard to replicate?
The dealer is there to make money. Relatively honest money, yes, but money all the same. Spending expensive labor time (figure the burdened cost of labor for taxes, SSI, benefits, etc., is at least 2x their take home, and then profits, dealer overhead, energy for the lights and heat, etc.) that isn't compensated, for an owner's wild goose chase, is justified to an extent.
Ive been pretty lucky though...
Example #1 - wanted to remove the dealer-installed cross rails from our roof rack on the odyssey. They were seized and when I tried to remove the torn bolts, they stripped out inside. The dealer could have charged me for this - after all, I stripped it. Warranty or not - it was my workmanship. Fortunately the dealer gave me a courtesy replacement due to some tsb or whatnot. But IMO even though the van was under warranty, I stripped the bolts - and I'm a reasonably good mechanic with the right tools and penetrating sprays. And, more than one stripped... They don't know my level of skill. Had I taken them in and they stripped the bolts it would have been on them. It was on me in this case. I was lucky.
Example #2 - accord hybrid battery was showing around 12.0v, which we all know is low to no state of charge. Took it to the dealer, they removed it, cleaned it, charged it, and put it on the tester. Tested ok... it's not used for much but turning on comtrol power to then get real power from the hybrid battery. Now, if I wanted to make a stink, I could have. Maybe I should have. But they tested it and said it was ok. They spent at least 30 minutes of time, on a battery. No charge.
