Why was I discriminated against. ????? Because of my way of dressing ???? they denied me the use of a bathroom ...... and 8 minutes later a well-dressed person ... if he had access ???? Very bad

You were discriminated against because you left. Now that most establishments have the right to deny service for your attire, for example restaurants enter without a shirt. Also take into account that restaurants have the bathroom for customers and it is their right to deny it to those who are not customers. If you were a customer and they denied you the bathroom then you really were discriminated against.

Try it again maybe
