You're far too kind.
The KMart I walked into could have been used as a set for a dystopian future reality "Escape from New York" style movie. There was neither customer nor cashier in any of the check out lanes. The woman behind the counter at the service desk had the demeanor of someone waiting for a bus.
Once I got her attention I gave her the SKU. She told me they did not carry that item. I asked if a rain check was possible and she told me they don't do rain checks. I informed her she was standing under a sign that proclaimed a "Rain Check Policy" but she held her ground and told me rain checks weren't done there.
By this time we had attracted the attention of several individuals wearing smocks similar to hers. I walked out before they decided I was threatening one of their own.
Fast, cheap, good: pick two.
