I just spent 5 minutes scouring the Caribou Coffee website and NOWHERE even in the corporate governance section is there any mention of Islamic ownership, not even any Muslim sounding names show up in their lengthy list of corporate personnel. PLUS, supposedly they are the 2nd largest (in number of stores) presumably behind only Starbucks? with 416 outlets, and I'm not even sure I have ever seen one.
I'm in New Jersey, near New York, and only Starbucks, Dunkin' D, and Seattle's Best have shown up here.
Wasn't easy to find.
