too early for humor

I've been really good about staying away from Hardee's and Jack in the Box for breakfast. Today I had to be at my HQ office at 8:30. On days when I have to work there I stop at JITB for breakfast. I ordered my normal supreme croissant and ice tea and the guy says "your total is three hundred eighty five dollars" (the total was actually $3.85) I pull up to the window and again he says "three hundred and eighty five dollars" I smile and hand him my money. He says "I said it was three hundred and eighty five dollars, i'm trying to retire today" It was too early for me to come up with anything witty to say. I thought it was kind of funny the first time, the second time it was less funny and the third time it was just annoying. I don't like when fast food people try to make jokes, just take my money and give me my food!
