Grocery Store Chivalry

This afternoon I ran to the grocery store to get more cookie dough for a fruit pizza (1 tube of dough is enough for a mini-pizza, a BIG pizza takes 3 tubes).  As I was walking up to the front door I noticed a man several steps behind me.  He shouted, "Let me get the door for you, Miss!"  I thought, "Wow!  A guy (other than my dad) making an extra effort to get the door for me?  Nice!"  And then I realized that it was an automatic door.  He was being funny.  Ha.
