Parking attendant have right to harass me when there is no sign in service station second I arrive

Im happy to follow the law if there is a law. From my 33 years on this Earth, in a legitimate parking spot, at a public service station of there is no sign saying i cant park there, does not give the right of seevice station employee to raise his voice and abuse me the second I step out my vehicle #sign #parking #car #service #servo #abuse #power #trip #australia
