If you're a student coming to my pharmacy for an internship, I wouldn't want you to work the register. I don't want a non-employee/guest handling money. However, if you are hired as a pharmacy intern, I would expect you to work the register. A pharmacist doesn't have to work the register as much as a tech/intern, but still you have to do it. There are times when you are alone or the tech is busy. Since we don't have a designated drawer per person, it is hard to blame an individual. However, if there is a significant shortage whenever someone is working, it should be looked into.
