It's your bag.
Do what you like and forget judgmental individuals.
I wouldn't do it on a staff bag. To me, that's pretentious. I don't carry a staff bag for the same reason. Someone gave me one and it stays in the bedroom, holding clubs. That's just me. If someone wants to bring one out to play, and I see them, it's fine. I don't look at other players on the range. On a carry bag, I put my name on it to prevent stealing. I also use a non-OEM bag. It's a factor - an anonymous, OEM branded bag is more likely to be stolen. It screams, "look at me! or "steal me."
Good point. I hadn't thought of the theft angle yet. (I like to imagine that sort of thing doesn't occur, but of course, that's just in my dream world)
Wouldn't that just say "that's my bag tag?" (From the theft perspective, I mean)
