I think it comes down to people understanding he’s upset that no one called him and asked and explained what is actually being done, I would also be upset and suspicious.

While on the other hand he’s saying no to something that is free and will be covered up practically instantly after the work is done (many of us know what this entails, while OP believes it to be a traumatic event to his lawn) and that may cost him or someone else much more down the road if he chooses not to allow it.

However everyone is downvoting for their own reasons. It just seems a bit dramatic to me. (I’ve had this done to me)
