What is the deal with infirmed old people demanding to see my receipt at Wal-mart at 2 AM.  I find this to be an insulting practice, to be audited by an invalid, being monitored on CCTV.  It's like the GD Airport.  One more reason to never go to Wall-Mart.  The guy demanding my receipt had a cane and was ready to menace me with it.  I asked him, why do you need to see my reciept.  He stated: "I just do."  As I held it up all crumpled, as I was going to discard it, but had yet to see a trash can I said: "What will you do if I don't show it to you? Call the cops?"  "I'll yell at you," he said.  I think I came off as abrasive, and probably fucked up his pace maker.  I just think this guy was rude.  It's two o'clock in the morning, and I've got melatonin and breakfast cereal.  I was so irritated that I nearly wadded up the receipt and bounced it off his fucking forehead.
