Maybe there is a logical reason for this, but...
Why do I get my prescription in a bottle that could fit 100x the amount of space that my prescription could take? I mean, a wildly large orange bottle, when the smallest size would do.
Isn't there a system in place that says number of pills + pill size = bottle size?
Or is it more like "Hey, use the giant bottles until we get a resupply of smaller bottles!"
