As many others have already posted, FI = options. The option to continue working if you enjoy it, the option to leave if you don't, even the option to tell your boss "kiss my ass" if you really want them to know how you feel.
I'm a few months away from being fully vested, but I've already mentally checked out of the place I'm at, and starting to exhibit certain behaviors I associated with being (almost) FI. I've started telling people "no" a lot more to projects, conference calls, business trips, etc, I'm not interested in. I'm speaking my mind a lot more, and not holding back my opinions as much as I normally do. I'm far less tolerant of BS and politics in the workplace now, and call people out for it.
So, yes, my tolerance for BS, both in and out of the workplace, is decreasing.
I'm also the kind of person to buy my way out of things, or buy better service, regardless of FI. If I can afford it, I will buy first class or business class airline tickets instead of coach. Hell, I'd charter a private jet if I could afford it (I HATE commercial airline travel).
Once, I had a fridge break in the house and the repair people told me it would take a few days to get new parts. I bought a new one instead.
To me, money buys options, and for me, those options include not having to tolerate BS as much, not sticking around at a job I don't like, and fixing day-to-day problems much easier even though it means paying more to eliminate them.
