i've never had to call either urgent number, and i've never had to call the cops at all. twice i would have had to, but for some reason they doubled me in the building (they had 2 of us working in the same place), and when both situations came up (once was an asthma attack a guy down the hall was having, the other was a bunch of kids kicked out by the RAs who were hanging around outside, waiting to come back in when security was gone) the other guy was at the desk and he took care of it.
and i think the only time i've ever called the non-urgent security number was last night when i was pakcing up and realized one of the supervisors had left her wallet on the chair when they'd stopped by.
thanks, i'm not worried i'll do badly (i've taken it 3 times already and it's always the same test...plus i decided to read the entire manual at work last night, just to go over things, and they're not going to fire me after 3 semesters just because i screw up a couple numbers), it's just a pain in the ass.
