Krispy Kreme Earnings Down

From the AP:

Shares in the doughnut-maker fell more than 10 percent, a slide that began almost immediately after Krispy Kreme announced that it earned $5.7 million, or 9 cents per share, in the three months ending Aug. 1, compared with $13 million, or 21 cents per share, a year earlier.

Might I suggest they are killing off their customer base?
