I bought a pack tonight at a local grocery store. I walked up to the pharmacy counter to buy them and the lady gave me a look like she was expecting something else as I put them on the counter. I asked if I could pay for these there and she, rather snottily, said only if I was getting a prescription, otherwise... and she pointed to the regular cash registers. I was kind of startled by how rude she was, but simply answered "Oh... okay" and went to get in line.
I felt a little awkward, but just asked myself "who really cares?" I much prefer going in and out as quick as possible, but I guess it wasn't that big a deal. I just figured the pharmacy people would be a little more professional.
