We just had an unsettling experience. At 8.45 the doorbell rang several times. Out in the street was a gas truck - our neighbor thought it was Zgas. We didn't go down to the gate so the young man outside pushed open the inside door to our buzon and was shining a flashlight on our walkway to the front door. In defense I had to go down to the gate to make sure they understood someone was here. I truly don't believe their main interest was in selling gas. A neighbor reported they got a similar visit a few nights ago. Just be aware.
