Ever have a friend get a warranty pushed on them for a cheap toaster repair? Mine did, and the guy looked so defeated paying the extra fee. It just felt like a tax on people who don't like conflict. Your buddy's right about the trust thing. Maybe only offering them on stuff that would really wreck someone's budget, like a main board, makes it feel less like a trap.

Got a night blooming cereus for that exact reason. The thing is a lump of sticks 364 days a year, then one random summer night it puts out these huge, crazy smelling flowers that are gone by morning. Makes the whole wait worth it.

Man, that sounds so rough. I've had clients get really snippy before, but yelling is a whole other level. Good on you for finding a way to step back instead of firing off a reply. Honestly, the guitar thing is a great idea. I might have to try something like that myself.
