 Shares of Cracker Barrel Old Country Store Inc. CBRL, -1.08 tumbled 11.5 in premarket trading Friday, after the home-style restaurant chain with retail stores inside missed fiscal first-quarter profit expectations, as cost inflation surpassed menu price increases, and trimmed its full-year revenue outlook. Net income dropped to 17.1 million, or 77 cents a share, from 33.4 million, or 1.41 a share, in the year-ago period.
