I was a fairly new FO and at the beginning of a 4 day, my CA briefs on APU starting after we land at each station. In other words, which station to start the APU and which ones to not. Well there's no way remember any of this, so on 1st landing I simply ask him again if he wants the APU on. Again I'm new and have no idea who has ground power and who doesn't. So he turns to me and asks "Do you remember the briefing I gave you about that?"
"Umm no, I got everything mixed up." So he huffs and reminds me that CVG is a no APU station. Got it!

Later in the trip we land in ATL. This is my first time in ATL as a pilot, ever! I called in our on and in times (no ACARS) and he yells at me for calling :33 instead of :36.
"Umm I didn't hear you say a thing to me about the times."
"Well I told you about 2 minutes ago. Aren't you listening?"

A few minutes later, I'm getting the clearance for our next leg. I was very careful to read the notes on the Jepps about how you only tell clearance your ramp and only read back the Squawk code. Well I slip up slightly but it was no big deal with ATC. The controller was very nice about it. Well then Mr. Toolbag asks me which runway he gave us...
"Umm, I have no idea" What airport gives us a runway in the clearance, I'm thinking? Again, I've never been to ATL. The guy didn't give a runway.
"He told you it was 8L."

So then he's had enough of me and lectures me about how I don't listen to anything. His briefings, how I should have read the Jepp pages on how to get the clearance in ATL. I was almost shaking at this point.

This was 5 years ago and I've learned not to take crap like that anymore.
