My former congregation's first KH had windows. The curtains were always kept drawn so no one could look out. 'Too distracting' was the explanation. When the new KH was built, no windows. Not one. The explanations depended on who you asked. Even doctors', dentists' and lawyers' offices have windows.
FedUp, your story reminds me of the time when local elders decided to lock the doors during meetings for 'security'. If you wanted to leave in the middle, you had to ask one of the 'attendants' to let you out. That lasted until someone tipped off the local fire chief who in turn read the elders the riot act. Turns out it was illegal to lock the doors in case of fire. They were courting a mass casualty disaster. I think they got off with just a warning.
