I now have 3 customers with these invisible DOG fences. Seems every year or so, I have one in my route for about a month, but 3 all at once!!! UGGH. All those little freakin' flags to go around (I refuse to string trim around them), and they always put the flags in the most undesirable places. In a few weeks, they will be removing every other one, and then in about a month, all flags will be removed. Question is....Should I be charging extra for this? One of them is the owners of one of my commercial sites' home, all under same contract, the other is on a property that I get well over the going rate (avg. $65/hr) and dont want to "Rock the boat". The third, I will definately raise a little for my inconvienience. How much do you think?
