Nah, just because one has muscles doesn't mean they know DICK about fighting. Tony has had a good long experience with fighting, knowing how to throw the beatdown, and take punishment.

Besides, the bodyguard probably realized as well that with 6 wiseguys in the room, if he tried to seriously fight back, he would default for good on his gym membership.

Anyway, as for Chris....imagine if it turns out that he indirectly help fund/arm some terrorists? The irony!
