My pharmacy, Rite-aid, has recently started closing from 1:30 to 2 for lunch. Maybe your place can start something similar?
I used to not eat properly when i was working either. It really wasnt a work problem, it was a problem of me not taking good care of myself. I remember being amazed at someone from my first job who would go to a restaurant and have the soup and half a sandwich special for lunch. He was a runner, not a big person, and watched his weight. Still i couldnt understand his not overfilling his belly. I was always starving.
