Rude waitress

So I'm with a friend and we walk into Wimpy Lenasia to have breakfast. We walk straight in as there is no body at the door to receive us. We find a table we are comfortable with and have a seat, a very rude waitress comes to us and shouts telling us that we are putting pressure on them to clean the table, why do we pick that specific table when there are so many other open tables. So I in turn told her that there is no pressure in her cleaning the table she can do so when she's ready, she carried on to say that she's the only one who saw us and now she has to clean the table. I asked her to stop shouting then she told me that there is a sign at the door that says right of admission reserved, so we were not supposed to have walked in without being escorted. Then she walked away and at the top of her voice told her colleague to serve us as she's not prepared to deal with us. My friend and I then decided to leave as it was clear that were not welcome because the manager was just standing there saying nothing. As we walked out the waitress said, yes let them go and clicked her tongue. I've had lots of meals at Wimpy and received great service, this was by far the worst I've ever experienced!
