he could have thrown a fit and ruined everyone elses evening. or worse, he could have gone out stabbing. seeing that this was a steakhouse, there probably were plenty of steak knives lying around.
If memory serves, Simpson was wearing cotton gloves before he "tried" to put on the gloves he was wearing when he slaughtered two people. Gloves on gloves. What a courtroom stunt that was.
I think he did a good thing by not creating a scene. To throw someone out for getting attention is hardly a reason and he could have easily made a big deal out of it.
