Did you lose your ID? I would ask for any paperwork, actually I would insist on it. Last time I had to buy Sudafed I was asked to furnish a picture ID and it had to be "valid" (current and up to date). If it is a store you frequent they should know you, at least be able to tell you look like your photo on your ID. Especially if you have a lot of prescriptions to fill on a regular basis. This is why I use only one pharmacy.
