Sure. But a little extra cash is a little extra cash.
I was a certified NYS high school soccer ref when I was in college. Reffed junior high, JV, varsity, boys and girls. Though each game paid well, you could only do one game a day, and it's not like I reffed every day. The assignments had to be spread out.
Granted, inflation skews my numbers, but I probably made less than $1,000 a year (well, just one semester, when soccer was played in the Fall). Yet, I distinctly remember doing all kinds of cool things (like attend the USGP in Watkins Glen and the Canadian GP in Montreal) simply because I had some extra cash on hand, beyond normal fun like partying and beyond whatever my parents occasionally gave me for "fun" money.
To a poor college student (remember when you were one?), an extra $1,000 or so is nice to have. So, why not make that a deciding factor?
