Service was poor and no professionalism

We waited 30minutes to order the cashier Thandokazi was busy up and down no communication no apology at all , then 30minutes later she took our order then we waited another hour for our order I asked the manager why they are not assisting with the order she just looked at me and said nothing I even told her that we coming from work we did not eat whole day. While we were waiting for our order I heard the teller saying to her colleague they only prioritize people that have money that's when we started complaining ,they finally gave our order infact she just put the order on the table and left the station and still no apology .
