My first field observation

This week's assignment is a practice observation.  We are to pick a public place and record what we observe for one hour.  I chose the coffee shop at B&N. While I can't discuss what I observed, I can discuss my feelings about the observation experience.

So there I sat for one hour fifteen minutes. Making notes. Watching folks.  Trying not to appear like a pervert or a noseybody. The experience was under-whelming.  Thankfully the activity level in the space is limited, so I had plenty of time to record what I saw.  However, I don't feel like I recorded enough or very much.  I didn't move from my seat, and with the except of one exuberant pair of young women, I couldn't hear any conversational details.  Was I to describe in detail each person's physical appearance? This observation stuff is harder than I thought.
