Guy representing that he was from SW Gas came to my door banging the hell out of it scaring me to death. He was demanding access into my side yard. I was not dressed and getting ready for work. Went to the door and told him I had to dress. Got dressed and I asked if he was SW Gas and then he told me he was an Authorized Contractor for them (I believe ELM). Guy's name was James, who I asked what would happen if I wasn't here and he said he'd hop the fence. I told him I had dogs. He said he had a right to do jump the fence. I told him I had to go, he said he would hop the fence. My choices were leave and let the dogs possibly bite him or leave the dogs in the house and go to work (potentially very harmful for the dogs and I have a pool so that would create a known risk to neighborhood children having access, or stay and be late for work. At that point I opened my gate under much protest. At no time did he offer to reschedule. When I had told him I had to leave he said he lawfully could hop the fence. I had to stay. They refused to work with me.
