I used to work at a UPS store.  We would pack and ship everything, it actually made our lives easier because we knew if we packed it there would be less damage claims.  My boss was a 300 pound whale but he only hired fit girls to work there because he said fat people were shitty workers...  I actually can't imagine having someone fat working there, we would have to lift really heavy and awkwardly shaped stuff and I was often on the ground in weird positions trying to bubble wrap things. Obviously those fats don't actually do their job but I can't imagine that store being in business much longer with them working there.
