I haven't been able to confirm/deny with the viewings I've had of Avengers so far, but some people on the Interwebz claim that the waitress' nametag says "Beth." I've scoured the Marvel databases for anyone that might resemble, and the closest I can come up with is Tony Stark's Bethany Cabe, who bears no resemblance in look or story to The Waitress.
So yeah, I don't think she's an important character after all. But I *do* think she had a slightly bigger role in the Avengers that's been left on the cutting room floor. Maybe deleted scenes will show more.
