Every time. Even if I have to hold up the ridiculously already long line in Wal-Mart. One time, I was driving on a 45 mph road and saw what looked like a paper bill getting blown across the road. I actually hit the breaks, turned around and parked on the road with my hazards on.. I chased this bill for a few minutes in the wind...All that for $1.00.
Luckily the road was mostly empty, though.
