I would unpack boxes, stack shelves, clean, serve customers. my co-workers were much more older then me so I didn't get along with them as much as id like. I learnt their system within the first shift. I didn't deal with the management side but I didn't have a problem with it.
Working at rivers there was always something to do that required time effort and detail. The work was never overly challenging but the most rewarding part of it all, making sure the customers left happier then when they came in.
