I can completely relate!
I had one foot already in retirement earlier this year, when senior management of another company came calling (I know all the regional folks very well) with a great offer. I agree to come on board short-term to help them - 6 months to a year and they understood.
On my second day there, while I'm out in the field, the national guy, who I don't know, calls me to tell me he's flying in the next day to go over some groundrules and that I should pick up this case study on the printer in my office, for us to go over the next day!
Sure enough, he flies 2,000 miles into my region and locks me in in a conference room for 8 hours quizzing me on this 50 page case study that he expected me to read in its entirety. WTF!
I'm an executive in my profession, fairly well-known in my field, and this national guy is pontificating for 8 hours how great he is and that this case study is actually about him and how successful he (thinks he) is! I was treated like a college student getting quizzed on the case study on minutia that I never read, like "when Mr. Jones, met the client, what was the first thing he asked?!!
While this is going on, people in my local office who are walking past the conference room - you could see in from the outside are smirking - apparently they know this guy's reputation of being a complete blowhart!!
Anyway, I held my composure, went home, decided that since he wanted to repeat this performance on Day 2, I was not going to let it happen. So, I walk into the conference room first thing on the morning of Day 2 of his interrogation tactics, and told him I'm quitting because I've never worked with someone so pompous etc. (He doesn't know that I'm financially able to quit at any time). Now he's completely on the defensive - because if the President of my company found out, (who knows me too)he'd probably be looking like crap that they brought me in and I'm leaving on the third day.
Anyway, here's what happened. The regional office senior management team begged me to stay (they know this guy is a nutcase) and interesting enough since that day, I've had minimal to zero interaction with this "national" person. In fact, he actually asked someone else (who I respect) to deal with me directly so things are better.
So Florida Tennis Player, isn't it great to be in the driver's seat. If they would have canned me or if I quit, no big deal at this point, right?
