As the smoky scent of grilling filled the afternoon air, Anthony Graciolett sidled up to the blue food cart with the crossed kebabs imprinted on its side and ordered a hot dog with sauerkraut.

As he munched, he went to the end of the line. When his turn came again, he asked for a hot dog slathered with mustard and onions.

After Mr. Graciolett waited in line again, he got pork souvlaki on a stick. For his fourth and final course, he ordered the chicken version of his previous order.

“I like a routine,” he said between bites. “I always order the same thing in the same order.”

Mr. Graciolett enjoys routine so much that he stops by the Souvlaki Lady on his way home from work at least two times every week.
