First of all, it depends on what kind of service industry you are engaged in, which is tall and needs professional technology, so I won't talk about it here. I will talk about the most common and lowest service industry-catering-hotel waiter.
Because I have worked in a hotel before, I am familiar with the work of hotel waiters.
What ability should I exercise? I really can't exercise anything. The average person is unwilling to do it. The waiters in my small restaurant are all middle-aged women because they can't find anything else to do. That's all I can do. No young girl wants to do this. The salary is low, dirty and tired.
Anyone who has eaten in a restaurant knows that no matter who goes to eat, they like to grab food, right? Finally, all the dishes on this table were served, and then another dish was added, soup was added, noodles were made, sauerkraut rice was made, acne and the like were kept urging, saying that they were all finished, just waiting for that ... Some people started to order less, and then kept adding vegetables, saying that they were all finished, hurry up ... You wouldn't know what was in the kitchen without staying in a restaurant. Whenever we are busy, we will laugh and say, we have started to fight. We are all ready to pee and drink water. I really can't take care of drinking water when I'm busy, and I have to hold my urine. Those who didn't take it on foot all ran away. Everyone's nerves are tense. Which guest came first? There are several dishes this week. Is the steamed dish ready? This dish is gone. Wash and cut it quickly. This thing is used up. Go next door and borrow some. Don't serve the wrong dishes ... in that small kitchen, you don't know how many times you turned and ran back and forth. This overloaded operation lasted for two or three hours. Sometimes you are slow and make a mistake, and you will be scolded. Sometimes I get angry with my guests. Sometimes I finally have time. When I wash my hands, my hands are usually a little greasy. I need to clean the toilet. Bad luck, you have to give way when you meet a guest who wants to have sex. Guests in the hotel are also in a hurry to go to the toilet. To make matters worse, there is something in the kitchen that tells you to go at once, and you have to hold back.
The working hours are relatively long, and there is no prescribed off-duty time, only the approximate off-duty time, and only the delay is not advanced. Go to work every day, no holidays. It's not good to ask for leave and deduct my salary. It's all a radish and a pit. Without one person, it will be much busier.
In addition, there is no specified time for eating, the food is late, and the guests have almost left before eating. Usually around 2 noon, around 9 pm. Eat early in winter. The food is not very good either. It's all leftovers, unsalable or unsalable dishes. Think about toothache, eat the food that the guests haven't finished eating and haven't moved much.
To say what ability hotel waiters have exercised, we can only say that they have honed their hard-working character and enhanced their ability to withstand stress in life.
