I once had someone try to give me a free t shirt at a 10k race and it had all kinds of logos all over it and was very poorly made. Yeah, it was free but it had no value so I didn't take one. There were tons of people trying to get extras to take home but for what? Do you really need ten free garbage t shirts from one of these events? I didn't even want one. Yes it might be free or even cheap but it has no value.
