Was needing roof access to replace a controller or sensor last year and a 30-something manager had to unlock door & escort me. I mentioned was nice to have stairs & a door instead of ladder+hatch. Their response was it was a detriment, as employees were going out and smoking cigs so they had to lock it. As an aside, they said "luckily nobody smoked pot and jumped off the roof". I chuckled and waited for the punchline, but one never came.
