I had plumbers out recently to replace a water heater.. after they left I went down to find out they had pushed the new one right up against the outlet the sump pump was using so I couldn't unplug that without moving the whole water heater. I'm not usually the one to complain that people don't take pride in their work but... it was a pretty visible and egregious error in a spacious and well conditioned utility room! Still haven't found anyone that goes above and beyond even for simple tasks.
