I guess it would depend on the situation and the severity of the flirting. If she interrupts our conversation to be obnoxious, then I would give her my nicest "**** you" smile and then carry on with my life. If it's something more inappropriate (like sitting in his lap, for example), I fully expect my boyfriend to deal with it properly.
Chances are the waitress wasn't trying to hit on your man in any serious way. If nothing else, it's an ego boost for him, and no harm done.
