What's the purpose of this corridor the workers walk through? Some kind of cleaning process, or a security scan to make sure they're not bringing in unauthorized devices?
Hi there! This is a totally off-topic comment, but since there is no way in HN to send private messages, I though I might as well reply to your most recent comment. I have been enjoying your comments about being a craftsman and working in a niche, and I think I am heading in the same direction. I could use some advice and would love to ask you a few questions, if you don't mind (email is in my profile).
