That is what I did. I also told him that I have a 3 strikes - then you're out policy, and this is strike 1.
He did come back the next week properly dressed, however every week after that there was always an issue with his characters or with the rules or why can't rules from a different RPG be incorperated into PFS. He would argue the point during game time as well as before and after each session until he finally received his 3rd strike.
I hope he does find a group that plays like he does so he can enjoy his revision of Pathfinder.
