The Tim Hortons by my work is the reason I've converted to Starbucksism.
Me:  Hi, Can I get an XL Double Double please?
Them:  Yes, of course.  1.49 Drive through please.
(Note that at this time the order screen says "Muffin")
Them:  1.49 Please.  Im sorry, we're out of your muffin.
Me:  I didn't order a muffin. I ordered a double double.
Them: What other kind of muffin would you life?
Me:  I want my double double.  I didn't order a muffin.
Them:  Ok, I make your double double.  Here is a cranberry lemon.
Me: I didn't order a muffin.
Them:  You must be hungry!
I paid and went on my way.  They made me take the muffin.  They also made what I can only assume is a 4 cream one sugar as far as my taste buds are concerned.
This happens 9/10 times.
