Sometimes I wonder is this is by design and using a dark pattern relying on the sunk cost fallacy and loss aversion... "I've already spent hours on obtaining this thing if I turn back now I've wasted all my time." It's what I truly believe some car dealerships utilize. They drag things out so that you don't actually "walk away" from the "deal" when they start pulling BS. Anyone who does this ought not be trusted. Why would/should I do business with someone that acts so shady?
