Donuthead

I stopped at a Dunkin Donuts drive-thru today to get some donuts for the office. The guy asks for my order, and I say "I want to get a dozen donuts."

He says "Seven?".

"No," I say as slowly, loudly and clearly as I can, "I want a dozen."

He says "Seven ? You know, twelve is really a better value."

I sigh and reply, "OK".
