If you feel threatened or unsafe due to the dad's behavior, it may be wise to consider taking appropriate action to protect yourself. Here are some steps you could consider:
Leave the area: If you feel threatened, your safety should be your priority. If you can, calmly walk away from the situation and go to a public place where you feel safe.
Document the incident: If you decide to pursue any action, it can be helpful to have evidence. Write down the details of what happened, including the date, time, location, and what was said or done.
Report to the police: If you genuinely feel that you are in danger or have been threatened, you can consider reporting the incident to the police. They can assess the situation and determine if any action needs to be taken.
Seek legal advice: It might be beneficial to consult with a lawyer or legal advisor about the situation. They can provide guidance based on the specific laws and regulations in your area.
Reflect on the situation: Consider the circumstances and your actions. If you were mistaken about the need for a business license, it's essential to learn from the experience and approach similar situations with more understanding in the future.
