balance at Tim Horton’s

So I’m at Tim’s having a bowl of chili and a decaf, thinking about what just happened.

I asked the woman at the till to get me a balance on some cards.  “You don’t remember what you have?  Really?” she asked in a childish voice.  WTH?  Why ask me this?  “All of them?  Well how many cards do you have?”  WTH again.  “I’ve only got three,” I say to her.  She scans the first one and asks, “Do you see the balance?  Can you remember that?”  <Ahem>  When she was done, I asked her, “You think I have a short memory, eh?  I’ve got dozens of cards for everything.  No, I have no idea what the balance is.”  I was going to ask her if she could remember my order, but I was too polite.  I now think I should have.

There is a balance between formal politeness and familiar friendliness.  She broke that balance.
