If the cops make it to the call for a "fever" or anything else inoccent sounding before you do you can count on it being a psych or just plain unpleasant person who they have already had a "consultaion" with that shift.
Just thought of one. As soon as you get your unit washed, cleaned, and restocked you WILL make a call on the dustiest/muddiest road and that call will be one that has the back of the unit looking like a tornado just blew through it.
