> I've seen a low-staff store - I was in a pharmacy

Walgreens, CVS, and the like are horrible to their retail employees and only care about retail business to the extent it drives more Rx business. You'll be happier using an independent pharmacy or one inside a retail business that would exist without the pharmacy, like a grocery store, and statistically safer, too.

They make a poor example if you want to extrapolate to other retailers.
