As a DM, where I can get frustrated is with players who line up like baby birds, beaks open waiting for me to wheel up the plot wagon and shovel in the plot so they can gobble it down. Drives me bonkers. And it's not rare. My last group, or rather, the one I walked away from a few years back - had three players out of 4 that just refused to be any kind of proactive. They effectively wanted me to open up the Monster Manual at the Letter A, and say, "Aarocockra, fight". It was such an incredibly frustrating experience for me. I'm dropping hooks, trying to bring in lore about the setting, constantly dangling ideas and getting absolutely nothing back. I actually went out and created THREE treasure maps for them (it was a piratey, naval campaign using Ghosts of Saltmarsh as a base) and they took the maps, looked at them, shrugged and never mentioned them again.
