Random Riddle: On Paper or in a Bar

I can be found on paper or sitting in a bar.
I can be found next to money that won’t get you far.
I share something in common with wheat and rice, Though you wouldn’t want to eat me because I don’t taste nice.
I can be kept in a box as well as keep time.
Can you come up with an answer to go along with this rhyme?

What am I?
