Customer experiences at Walgreens vary significantly by location and department. Some encounters are described as the worst ever, with staff being argumentative, combative, and rude. Pharmacy visits can be frustrating, with unexpected closures and long wait times even with appointments, suggesting a need for more help. However, other experiences are positive, with certain managers handling situations well and staff at specific counters, like the makeup register, noted as being nicer. The service received depends heavily on the individual store and the specific employee encountered.
