Did that for pens while employed as a pizza delivery driver nearly two decades ago. Customers would regularly sign for a credit card receipt with my pen, hand back the signed receipt, receive pizza, and somewhere in the object-management process wind up still holding the pen. The cheapest pens were like 8 cents each at Costco, so it literally wasn't worth my time to try to make sure my pen made it back to me.

I do that for myself because it drives me crazy when I get held up from what I'm doing by not having what I need, cables, adapters, etc.

I have also been quite generous with friends, trying to teach them the way. However, I've found that I'm just enabling bad habits in careless people, and before you know it I've run out of anything popular. So now, I still flood my zone, in secret, and let others fend for themselves.
