I keep several pairs available and very visible on the sewing table. When someone is looking for scissors for any crazy reason, they can use them. The secret is that I don't tell them that it is ok. If I catch them with them I pretend they are using the good ones and I still make a big deal out of it, but the truth is that I couldn't care less. When I need my good ones I make sure no one is around, I get them out, use them and hide them again. I know they have been to the bathroom, the garage, even the car.
