Hello my name is ***** ***** I will help you.
What would you like to know about this today please?
Have you complained to the council?
You are permitted to have who you want or not want in your shop. The police don't need to remove them but you can ask them to go.
It's not illegal what they are doing but morally it's wrong.
But you can ask them to leave.
Can I clarify anything for you about this today please?
