Service is poor compared to Walgreens of 5 yrs ago. Compared to other retailers today, service is a little above average. It's all about cost control. Everybody is doing it. There is no alternative. Suck it up.
My experience with WAG's service, on the whole, has been very good. I do have the impression that they have fewer employees per store than they used to. Still, the employees are knowledgeable, accessible, and usually friendly.
The pharmacy staff are often very busy. But, they know their stuff and take the time to answer questions.
The overall experience is very efficient and satisfying, especially compared to their competition..
