I have a customer that has been with me all summer long. I showed up today to mow but in this drought he asked me not to (first skip on him this year). He continued to say that he had a tree in the back yard that he would like taken down. I told him since he has been a great customer this year I would do it for less then I normally would. Normally I would have charged about $250.00 but I did it for him for $185.00. The tree was pretty well trimmed during its life. There were no branches exempt at the top. Even at the top I think there was only like 5 branches. Because of close quarters I had to take it down in levels. The top half went great! The middle went great! Then I got to the bottom 7 foot. The inside had steel all over the place. Come to find out there was a fence there when this property was a farm, years ago. There were nails all threw out the trunk and an old metal fence post. There were no signs of these objects on the outside of the trunk! A 2 hour job turned into over 5 hours and I destroyed to chains for my saws trying to find places I could saw threw. Here is my question? I already agreed on a price and had the job almost done when I brought the customer out to show him the problem. Should I have raised the price? I didnt but was expecting some kind of tip. Didnt get that eather?
