My sister, while she was a student, had a waitressing job at a fancy golf club. One day she was in the kitchen with the chef, when a mother rat and her babies crossed the kitchen towards the restaurant. They'd had the door open in the kitchen because of the heat, and I think they'd come in from outdoors. Quick as a flash, the chef grabbed a pot of boiling water and chucked it over them. 
Even though this happened years ago, my sister hasn't forgotten it and it came up when we were chatting the other night about past memories.
I KNOW that I would have frozen on the spot and brought the whole place into disrepute 
What would you have done in this situation?
