There is no job that is “below” you.
Don’t be afraid to do the grunge work. Don’t drag through mundane work, make it a positive! The “little jobs” are given to new people just starting off because it’s the companies way of seeing if they can trust you. My professor gave that advice to my class one day. She said “If you can’t get a coffee order right, how can they trust you with the important stuff?” You have to admit… she’s got a point.
