Are aid stations at races meant for only those running the long distances?

I'm running my first trail race that has 4 mile, 8 mile, and how many loops done in 3 and 6 hours. I'll be running 4 miles. I plan on grabbing snack from the aid stations at end of the race but I feel like because I'm not running that far or need it during the race I shouldn't. Most of the participants are doing 4 miles.
