OMG!!!!!
OK, here? You have this HUGE store. Somewhere in the back corner is a little window (or counter), behind which a couple of people in white coats (the pharmacists are usually men, the assistants women) are lurking. After you stand in line for a while, you MIGHT be able to get their attention. If you have a prescription, you give it to them, along with your birthday, address and lots of other identity-thief-drooling information. If you wait for it, they'll tell you 20 minutes, and you'll be there an hour. Or more. If it's been called in? You give them the name and birthdate, then verify your address. Depending on what your insurance pays, you then sign over your next 5 pay checks.
OR, it's just a pharmacy - nothing else - I haven't ever been in one of those. Not very big places.
