hahaha, my job is just has hard as yours and i spend just as much time on my feet (i'm not a shelf stacker, i was for 6 months before doing my knee), so get a grip if you think my job is so totally easier than yours, and i get paid poor wages compared with a posty, but we don't complain, we get on with it, because some money is better than no money

(btw, i've been solid at the same job for over two years now, gone through my fair share of problems including losing wages to the incompetance of the pay role staff, losing out on holidays because they can't afford to let me have them off, over 40 hour weeks when we were short staffed, damaging my knee due to the hard conditions etc etc etc, don't try to lecture me you arogant berk)
