This is my first commercial account. It is a restaurant that needed some planters installed, parking lot cleaned and 13 yards of mulch put down. Well I am 80% done with the job. I have one more area to mulch. The agreement was to weed the beds.Which I did. There is one area near the dumpster which has what he calls weeds. They are like 7 feet tall weeds that look like trees. He wants me to clear that area. I told him that when we discussed weeds we meant "normal everyday type weeds" I told him I could for an extra charge but he came back saying he thinks I should do it as part of the original deal. I am thinking I should just suck it up and do it. This account could lead into some more jobs for me. Any advice would be appreciated. It would probably take me about an extra hour and a half to do.
