This particular Walgreens is the closest to me and a short stop after my yoga studio.
Pharmacy: Always a line. The pharm techs are usually friendly but some are incredibly apathetic and do not want to speak to customers. The pharmacist I've talked to is nice.
People are always asking for money inside and outside of this Walgreens. I was approached by a homeless person with a request for some purchases, and people are always just outside the door.
The women in the cosmetics area are service-oriented, always ask how I am doing and are chatty while I check out.
