My biggest grief is pushing out of ATL and then taxing for 9L M2 intersection. Not to start a North vs South battle but North guys always spin both right away. South Captains have this personal goal to get to M2 with 3 minutes on the engines. Which sounds great for fuel saving but overloads the FO. Gotta spin the engine at the last moment possible, usually when your taxiing eastbound and about to pull a 180 onto Mike. Not the best time to be both heads up and down. PA to the kiddos, wait for the FA to call back, while communicating with ground, running the Delay afterstart, safety briefing for Takeoff runway, BTO check.... all in less than three minutes.

I take my sweet time to make sure it's all done correctly, but I can see a new FO being rushed and mistakes made.
