I see where I stand - Knowing you're not the main dish but you're still on the men

Knowing you're not the main dish but you're still on the menu and you're not going anywhere.

I see where I stand, I'm the snack that gets ignored but still shows up.

I see where I stand, I'm the extra player who's not in the starting line but still plays.

I see where I stand, I'm the person who's not the main event but still gets the job done.
