Zero customer service

Clearly placed my order and paid - was told it would be 20 minutes waiting time. (First mistake - did not receive a receipt). After 20 min, followed up with my order which they brought 2x 514 but no sushi (2nd mistake). The cashier apologised and said they would make it now. After 15 min, she called me to fetch my order, with the completely incorrect sushi (3rd mistake). Then she called the manager who decided to help the queue waiting to order first before seeing to my issue (4th mistake, as there was more than one computer available). After 10 min, he apologised and said I should give them some time to make my sushi order. At this point, people who had tables inside were leaving before me. After a further 20 min, the order is now complete and the waitress calls me in TO PAY! (5th mistake - I paid when I ordered) She hands me the packets, says 'thank you for understanding' and I double check to find that they didnt even give any soy sauce for the sushi. Are you kidding me! Atrocious! Zero focus! The customer definitely does not feature on their priority list.
