No. I've been sat here the whole time since I came down. I've been talking through the door to try and get some sort of response. I thought maybe he just hadn't heard me for awhile, but there's not anything going on that I can hear that would block my voice.
Unless he's all the way in the back of the shop. But if he was, I don't think I would be able to hear him. The door would muffle it equally going both ways.
