It just automatically happends before I really am desparate for a refill. I don't think you lead question is particularly useful as we usually don't interact with anyone at Amerigas except when negotiating a contract. When I have talked with your staff they have always been both polite, friendly, and informative. Not much more I could ask for except the option of natural gas!
I've been with Americas for 13+ years. I've always liked the service I've received by the staff in the Bellaire, MI office and the courtesy of the driver's when I've had the opportunity to speak with them. We are gone for some of the winter and they always make sure we don't run out of propane. We appreciate the good service.
