Be prepared to be on your feet for a long period of time doing possibly the same job every day. Do not slack off for a long period of time because they will take notice, if you arent working and take that very seriously. Come to work with a water bottle to stay hydrated when working. Breaks only last for so long, so do not bring a feast to eat during the break. If you start to feel unwell go to their health center, do not continue working if you get worse.
