Costco CEO, Jim Sinegal, stated: "Our announcement earlier this week of the food stamp test in our two existing New York City locations was apparently misunderstood by some. It was always our intention to include the new 116th Street location, either as part of the ongoing test or as a permanent fixture depending on the exact opening date for East River Plaza. When we announced that the test, if successful, would result in adding food stamp acceptance to all New York City locations, we did not mention 116th Street specifically because we wanted to be inclusive of all planned locations, some of which have not been publicly announced. As a result of a phone call I received from Congressman Charles Rangel, we now understand the special sensitivity in New York to this long-awaited project in his district. So, to remove any doubt we may have inadvertently caused, Representative Rangel asked that we make this clarification. We are grateful to Mr. Rangel for the respect he showed for our company in bringing this to our attention. We appreciate that he has a very special interest in the well-being of the people in that neighborhood, and respect his point of view."
