Wendy's shares have increased by 15 percent as Nelson Peltz's Trian group has suggested to buy the burger chain for $1.4 billion. This offer comes at a time when Wendy's is dealing with challenges such as soaring beef costs and escalating competition. A confrontation at a Wendy's restaurant in Los Angeles, involving a man with a knife and another with a grin, has spread widely.
