At a previous service, some twit rounded the corners off the #2 spark plug, so now it can't be undone with a socket. I just discovered this today, while changing the plugs. Not severely rounded, but bad enough.
Does anyone know how a mechanic would get around this? I don't want to go to the mechanic for one plug, but I might have to.

You can buy sockets/spanners specifically to deal with rounded corners so just ask your local auto parts dealer, they grip on the flat surface as opposed to the edges.

Why not go back to the garage and get them to remove it
