The short answer is almost certainly not, and the real reason is the very first thing you wrote . . . that you were being overly sensitive. Given that the police took a pass on any criminal charges, the civil arena is not of much help to you. the sort of conduct you described is extremely rude and offensive, but it is not the sort of conduct that is so beyond the bounds of civilzed behavior that it will support a claim for intentional infliction of emotional distress. Additionally, with regard to any negligence claims, there is an issue of whether a duty is owed to you and the scope of the duty owed. In sum, any civil action filed would not be worth the time and money to file it, and it might be viewed as frivolous. You may be able to get some satisfaction by complaining to the BBB and/or posting appropriate and accurate comments on one or more websites on which the business is rated. Otherwise, the entire episode is simply a testament to the lack of civility present in modern society.
