How do I find out if this job losting is correct?

I need a job, and I live near a fred meyer. Years ago I saw a listing of theirs that said "courtesy clerk/bagger". I applied thinking I was going to be a bagger. At the interview, they said they don't have baggers, and I'll be pushing carts, and cleaning bathrooms. I ended up chickening out when they called me for orientation, and told them I got another offer. Well, years later, I see the same listing. "Courtesy clerk/bagger". Im pretty sure it's what I think it is. (A cart pusher) but I dont want to go to the interview and find out its not what I think it is. Could I just find an employee and ask? I have communication issues, so situations like this are difficult for me.
