We are all assuming the conversation was civil right up until the time "Tool Bag" exploded. It's possible that the conversation was something along these lines:
OP: What did you train in?
TB: Cessna 172
OP: Oh yeah, I trained in a Cessna 172S! So, you built your multi time in Seminole, I had a Baron that I could use for FREE!
OP: When did you get your CFI?
TB: (facepalm) 2005.....
OP: Oh yeah? 2004.....pooyah!
OP: AND.............how many hours do YOU have?
TB: ****BOOM******
Not stating it happened like this. IF your intent was truly to determine if your qualifications were enough for TB's company you could always discuss the particulars without asking him "personal" questions. MAYBE sonthing along these lines:
"I am a CFI/CFII with "X" ratings and about "Y" flight hours. Do you think that would be enough for consideration with your company? I would really like to fly for this company..."
Just thinking out loud here..........
