Question about job application?

i'm applying to firehouse subs & there are 5 positions i would be willing to do: waitress, hostess, cook, prep cook, & dishwasher. under the 'positions applied for' should i put all of these? or does that make me look pathetic? should i only put one or two? or should i put them all so there's a bigger change they'll hire me because i'm willing to do more things? thanks!
