Yep, I'll pick one up almost every time I see one.
I tend to stay off my phone while walking thus often see one. Be curious how many others are walking while distracted thus don't see past their screen.
edit:
Quoted from joemagiera:Is your picking up (or not picking up) behavior different if you're with someone else?
nope, if you don't like me for picking up a penny, you can move along.
