I continue to eat sandwiches from Bildner’s, and every time I take a bite of one it reminds me of what I did wrong. I didn’t wait to see if this good idea from the neighborhood would actually succeed someplace else. Successful cloning is what turns a local taco joint into a Taco Bell or a local clothing store into The Limited, but there’s no point buying the stock until the company has proven that the cloning works.
