I found an old box of dog stuff recently. Old toys, leashes, and the like that I thought might be useful to the local pet shelter. So I took it down and handed it over to a volunteer who started sorted out gems from the junk. It was towards the bottom that they found a choke collar that was nothing more than a set of thick, unvarnished rough steel links that looked heavy enough for a grizzly. Dull and obviously brutal.
They looked at it for a second and hesitantly asked, "Did you do a lot of work with aggressive dogs?"
"God no, I'd never use that on a dog." I said taking the heavy chain, "Its an old girlfriends and I'll have to get it back to her."
"Oh." The volunteer looked relieved then quizzical, "...did she work with aggressive dogs?"
"Nope." I gave them a bright smile and promptly exited before any more questions could be asked.
