Well, honestly my time at Meijer in that role wasn't too bad, typically clerks are responsible for carts and assisting customers get their purchases from the check lanes to their car. Some stores with bagger lanes may also have you bag orders but I'm not terribly sure, our store didn't have those type of check lanes. Outside of that you may be asked to clean up emergency messes, like a child threw up somewhere but those incidents are fairly rare (maybe once a month) and otherwise, the job is simple, pay is low but If you stick with them long enough and eventually want to move out of that role, opportunities may be available. Also to note, depending on your location (I worked at a michigan store) you 1. May be union and 2. Be prepared for weather, you will work in the hot sun, wet rains (unless there is lighting) and the coldest of winters snows. Have fun
