Back in July a man with a replica handgun and a knife attempted to rob a Starbucks while wearing a Transformers mask. A 58 year old customer came up behind the robber and hit him with a chair. The robber attacked the customer and they began to fight. Both men were stabbed during the fight. Now, the mother of the robber says her son is suing the man who stopped him from robbing Starbucks.
