It doesn't matter, after ten minutes, I'm in a zone. In New York, I wear clothes with lots of pockets and take taxis. Go early for the best catches, late for the best deals. When leaving early in the morning, remember to dress in layers so you can remove clothes as the day warms up. Some people like company or have a need for a second opinon.
Some people go for the bargains - others enjoy people watching.
I prefer to hunt alone - no distractions, no lagging behind, no competition, no opinions. Hey, this is way beyond need, buddy. This is about the art of the hunt. Get out of my line of fire. Here's a dollar.
