...something dumb he once believed.
My partner and I got Subway to eat while watching Survivor recently.
It reminded me: a former colleague once told me that one of the ingredients in Subway's bread was sawdust, and I believed her. In fact, I didn't even question it or look it up—of course a giant fast-food chain would cut corners and use a cheap product in their food.
There was a location on the same block as our office, and the Subway app always had good coupons, so I continued to eat there multiple times a week for years, sincerely believing I was consuming little bits of wood every time I did.
What can I say, I'm a sucker for a deal...
