Has anyone done an out of warranty battery replacement on their Apple Watch. I have a Series 0 SS Apple Watch and I'm amazed at the pushback I received in the Apple Store attempting to just get a simple battery replacement done. Is this what I can normally expect from Apple Stores in regards to service?
My Series 0 Apple Watch is over 3 years old so Apple Care has expired and it is out of warranty. I expected to pay the Out of Warranty battery price to replace the battery as the battery life isn't holding up as well as it used to for me. Apple lists this price as $79.

What I thought would be a simple in and out deal turned into over an hour of diagnostics and the Apple Store employee constantly telling me that the battery tests fine and that they likely won't replace the battery because it passes diagnostics, but I can send it to the depot anyway and "hope" they replace it. He also noted on the work order that Apple may decide to charge me more to replace the battery if they replace it anyway and the battery tests fine.
Why would I have to "hope" that my battery is replaced when I'm paying explicitly for a battery replacement out of warranty? Also, does Apple routinely jack up the price on battery replacements when they arbitrarily determine it is a "good" battery? I can understand Apple pushing back on Apple Care or warrantied battery replacements, but I can't understand them pushing back here.
