I've conspired in the death of another rat on the office floor. This one was more of a struggle and required the coordination of three people for five minutes to corner and then kill the poor blighter. He and another had fallen from the ceiling and after a brief scurry around the computer lab had bolted into our office from where he'd never return. For three minutes of the pursuit a service manager (not our staff) stoutly stayed in the corner on what would presumably be a very important call. Her bravery was shattered when it dashed to her corner crawled up her leg and into her jacket. One staff member was in tears and she hadn't even been in the office when it came in. Another felt uncomfortable just being in the office again.
If my boss had been on duty, he might have led us all out. I didn't feel brave enough or qualified enough to do that without some ground laid with the centre manager. He reacted quickly coming to work and getting an exterminator for the next day.
