In a previous career, you ordered things by the PIECE. If you wanted 100 of something, whether it came in a pack of 10 or 20 or 100, you ordered 100 and everyone knew what you wanted and it was delivered accordingly.
In PHARMACY, you order by pack size.
Yeah, I learned that the hard way.
During my first month as a pharmacist, I had to place an order using a website directly linked to our supplier. I needed to order generic extra strength Vicodin. It comes in bottles of 100 and 500. I needed to order a bottle of 100 as a special order. So yeah, I put in the quantity 100.
The next day I work the late shift. I walk into the pharmacy. The pharmacy manager is on the other side of the room. She raises a finger in a "come here" gesture and says "Mr. RxMan... come here." She asks how I'm doing. This is instantly troubling for she never expressed any interest in how I was doing before. I said "Fine." She says, "Have you seen the back room yet?" I walk back there to find 10 boxes of 10 bottles each of 100 count generic Vicodin ES. No one at the supplier who packed the delivery thought this was unusual. Neither did the driver. They just delivered them without asking, and here they are at my feet. Although the tech was getting a big kick out of it, the pharmacy manager was not amused.
