All the other people who have ordered meds before you. Also where you told a two hour wait time in person? That's a little suspect if it's not a huge order. I worked a very busy pharmacy, and if you are waiting in store we rarely had to ask more than a half hour. In fact a half hour is rare, but a rush when we are short handed....
But if you call ahead or order online, that yea you are just in the line of a few hundred people who needs rxs filled.
