Me: you'll be done with chemistry by 5 right (it was 4:50)
Grad student: why?
Me: there won't be any water in the building after 5
Grad student: Oh, I don't need water.
Me *my head is exploding*: The safety showers/eye washes/sinks won't be working! It's a safety thing. Also no bathrooms.
Grad student: Oh.
At least I think I caught all of the people who don't read their emails?
