no way!! it is definitely NOT pathetic to put. it shows that you've had experience working an awful slave job.
i put on my aadsas app that i worked at a (crappy) fast food restaurant for a year in h.s. and that it "helped develop a strong work ethic for me"...which it really did. everytime i started to not work as hard in college, i would remind myself of how horrible a place i used to work and that i never wanted to work there EVERRRRR again.
i think that's what helped me do so well in college but for real. you've seen the whole "value of a dollar" thing too.
