The Monkey House Strategy
1) Prevention. Have a reputation for throwing feces at person who come by your office and ask you upsetting questions.
2) If at the meeting, bring an umbrella. When asked, explain it's just that sort of behavior you expect from them and you simply thought it to be prudent.
