It wasn't a fancy restaurant, it was the kind of restaurant that doesn't have table service, you order at the counter and you wait for your food at your table (they'll yell out your order and you go pick it up). There's no station for you to put your dirty dishes/ bowls or plates so the workers still need to do some clean up.
I went there today to have lunch with my daughter, there was just one dude there working. It took him about 15 min before he could take my order, he kept apologizing, but he looked really busy, I told him I'm not in a hurry and he can take his time. In the mean time, while he's cooking, he was also answering phone calls, taking orders on the phone, accepting doordash or Uber Eats, and greeting incoming customers. At some point there were too many people waiting to place an order and he had to leave the food cooking on the wok, take orders at the register, going back and forward, it was crazy.
The restaurant even has this “you will get your food within 12 min after you placed your order” thing, but none of us was crazy enough to complain that we didn't get our food on time. I was angry, not angry at the worker, but angry at the restaurant. I went to Twitter to tag the restaurant and complained, I doubt they'd do anything about it. I don't even know what I could do. I don't believe that the restaurant cannot afford to hire another poor minimum wage worker.
