Not at all.
I probably annoy people at the day school that leases space from our church as I set the alarm anytime I am the last to leave. My theory is that anyone on their staff that has a key to get into their locked office should be responsible enough to be given their alarm code. There is no point in paying for an alarm if people don't arm the building. And they should be able to walk 30 feet along the hall to be sure all the offices are empty if they aren't sure.
