This is indirectly related to lawn care but if it has to be moved so be it. I was spraying today and I was working late if 6PM is late so I have 20 gals of spray left and I can do 1 more 10K lawn. It was slightly breezy but not terrible because the yard was completely protected by trees and evergreens. I have a new customer who just moved in over the winter. The lawn needed help and my first pre em/fert did good. Its now time for the weeds. I pulled up on a suburban type street and place my flags first. I then start the Walker because that has the sprayer on it. I start doing the lawn and the neighbor is in his front yard and sees me, we make eye contact for a second. He sticks around out front for a bit and goes away. I spray the entire front side and 3/4 of the backyard when he appears at the fence. Hey what are you doing, he asks. I told him that I was spraying for weeds and he said thats what he thought. He then asked if I always work this late because most guys do this during the day. I said that yes I work late and the wind usually dies down later in the day. He said that he has kids that can't play in the yard because it smells (speedzone). I said that as it dries it usually smells. He said he has 2 kids and one has a heart problem and on and on. I listened but thought, do I have to be a mindreader too. I also stated that I did not see any children playing. He said his garage smelled and he became more agitated after I asked him why he waited almost 25 minutes after he saw me in the front yard. He said so if he would have asked me to not spray, that I wouldn't. I said yes. I have no problem coming back if someone asks nicely. He said that he was gonna talk to the homeowner (for what I don't know) I apologized for the inconvenience and stayed professional. He just walked away and I could tell he was pizzed. I was a little mad inside because he seemed to have baited me by letting me go so long but I just stayed professional. I finished 2 minutes later and then knocked on the homeowners door to explain what had happened. No one home. I e-mailed the customer amd am awaiting a reply. What would you do? I am working within the rules and the smell was just the product drying. I think he is mad because that lawn is looking much better than his.
