Oh god, this sounds real fucking stupid, but I found a hair in my drugs. I feel like I should tell the vendor, I'm sure leaving prints/DNA/etc isn't a good idea. I'm not fussed cos I just tossed it away, obviously. Do you guys think I should say anything?
I don't get the downvotes on this. It's a legitimate question.
I, personally, would tell the vendor. It may or may not be important to him/her, but you won't know until you tell them.
