Go- But Go Before You Need To?

Our office administrator sent us a fun little email a few days ago....we are supposed to go, potty that is, before we need to.
Say what?

Due to improvements (anything here would be an improvement) to our "water lines" the water will be shut off at 4 p.m.! So, for those of you working stiffs, like us, this will be an entire hour before we leave work for the day. What are they thinking? That's like asking a child not to crap it's diapers!

We can't get co-workers, and strangers to our building to courtesy flush when it is clearly needed, now you are telling us we can't use the bathroom for an entire hour (actually, the service is overnight) while at work??
I am sure the day after will be a fun one, filled with unflushed commodes and the odors to match.
