A former IBM consultant has shelved his suit and six-figure salary to sell Belgian waffles around the city from a yellow mobile food truck. Thomas DeGeest, 37, of Chelsea, said a heart-to-heart talk with his wife last year made him trade in his corporate life for an apron, a set of waffle irons and a "Wafels and Dinges" truck. "A waffle makes people smile," DeGeest said.
