My mother's job is a waiter in a small fast food restaurant, but because of the shortage of staff, my mother's job far exceeds that of a simple waiter. One person does what several people do. Standing at the bar to sell things, ordering upstairs, preparing things for them to do after ordering, sometimes doing it yourself, answering take-away calls, packaging take-away, making milk tea, sealing milk tea, mixing special milk tea, mixing juice, milk, making smoothies, snow bubbles, making hamburgers and sometimes even frying eggs. In fact, it is not difficult to do these things. The most difficult and terrible thing is that due to the shortage of manpower, sometimes a person has to order four or five tables and then deliver them all. Worst of all, most of the guests are impatient. Seeing how busy you are, they are still yelling at themselves, and my head is getting bigger. Some guests are even less qualified and will scold you, whether in person or behind your back. As long as your mother hears, of course your mother is not easy to mess with. She spoke in front of them and quarreled with them. I also admit that I have a bad temper and a bad attitude. In this month, my mother quarreled with the guests many times and drove them away.
