At the outset of the Season 3 Seinfeld episode, "The Limo", Jerry and George are stranded at the airport. George sees a limousine driver holding a sign that says "O'Brien." He talks Jerry into posing as O'Brien and Murphy to get a free ride.
As they go to approach the limo driver, a traveler asks Jerry and George if they know the time. George tells the traveler dismissively, "There's a clock on the wall.", and pulls Jerry away.
This interaction doesn't seem to add to the scene. By now in the series, George's character is well-developed as a misanthrope. It does ring true to Larry David's aesthetic of unwarranted advances by strangers in public.
Ultimately I am wondering if I am missing something with this scene.
