I have a steno notebook that has a page for each complex shop. Simple shops get a few notes on the first page of the survey. For complex shops I need target name, my alais, my fake phone and email info, info on what model (car, house, etc) I am shopping, info on competitors that I am considering, etc. Lots more for when I am shopping for assisted living for my "loved one," since that person also needs name, age, and personal details. That notebook stays, out of sight, in my car while I am in the shop. By reciting all of the relavent info a few times on my way to the shop, I can almost always remember it all. ("Punting" has its own place in complex shops, lol.) It's great when I get to fill out that "guest card" early in the visit, while my memory is most fresh!
