Hi,
I need a little help with the model I created. So far I have built the model from when the product enters the warehouse to when it is placed on the store shelves, but the last part with the customers is bothering me. I have searched the internet and can not find satisfactory information anywhere. It's about customers entering the back of the store and how I connect them to the system so they go to certain shelves, buy products and finally pay and leave the store. I am including the model.
Thank you :)
