There is probably some statute or other that they violated, but the question is whether the cops would be interested in figuring out which statute it is and then tracking down the guys who were yelling at you, witnesses, etc. The probable answer is "no" since all the guys would do is deny saying anything.
Ignore the idiots. Don't let them determine whether you are going to have a nice evening or not. You might also take your business to a better neighborhood where such behavior is frowned upon.
