Sounds like it could be. It really depends on which of those duties are actually emphasized. If the stocking & cleaning is 50% of the job, then that sucks (but still you're basically "paying your dues" to get better opportunities). The pt contact is what matters. Try to get as much of that as possible; however, humbly doing whatever is asked of you is going to say a lot for your character (which will hopefully be reflected in your LORs).
