Only in the airline industry is it the customer's fault for not correctly identifying that the company employee was wrong

This applies for many things on United. Them processing upgrades but not bothering to get the flyer from their seat etc. Knowing that despite the captain telling you that you are delayed for mechanical on a sunny day, that United will file it as a weather delay or ATC. From what I can tell, they delay a flight due to mechanical, and then 2hrs later when it is finally fixed and ATC no longer has a slot for them, it then becomes an ATC delay. They have lost the trust of everyone from top to bottom.
