The hotel where I gave my presentations literally overlooked the atrium to a large shopping mall. I did a total of six back-to-back presentations together with an associate. Each time he started speaking I ran out to the mall returning just in time to present my section. On the first excursion I purchased a pair of comfotable shoes to relieve my blistered feet. The second trip yielded a new shirt (I had packed for 2 days, not realizing I was booked for a three day trip). Finally, I returned with a workout bag (to carry my boots in; I had packed my clothes in my computer bag and had no other luggage). Shopping in precise 20 minute intervals is a very entertaining way to go about the process.
