I have fired clients several times. Have had them decide..........insist, that I top a tree when I was in the middle of a prune, fired. Had a guy keep walking under us at a removal, had several more to do, finished the one, told him to get someone else for the others. The best tho, had a old dude we were doing a removal for, kept stopping us to ask how we are going to do this or that. I was using the bucket and he would run out and wave me down and say "so what exactly is your plan on that one" after a couple trips back down I was done. I had barley begun to set ropes and this guy had already held me up for a hour. Last trip down I told him I was done "wait,wait,wait, I'll stay out of your hair" I just smiled and said "YA GOT THAT RIGHT"
