The only one that really annoys me is having to build a grain exchange in 0 turns to avoid having every general be an Incompetent Trader. "Sorry folks, I was going to build a militia so you would have some protection when the masses of rebels who surround our fair village come raiding, but instead I built you this lovely grain exchange so they don't have to raid each of your homes individually. Now they can just throw a torch on each as they pass by on the way to our centrally located unprotected grain stores." The rest of them I can deal with, these guys are humans after all, and everyone has vices. Even me 0:)
