"I also noticed one thing." Jiang Yao said: "When the waiter gave them coffee on the table, this person's body stiffened, and the hand under the table moved the hand that was originally going to drink coffee, but he shrank back, and his eyes stayed on other people at the table for a long time, he was observing how others drank coffee, so this person should not have drunk coffee on this occasion before today, because he has not seen much of the world, so he is easily nervous, I was nervous when I passed by, and the waiter was also nervous when he served coffee, and in the end he also chose not to touch coffee, I was afraid that I would find out if I made a mistake, or that I would be ridiculed. ”

"Can you guess what this person's profession is?" Lin Tuanzi said: "It should be hard to guess, right?" ”

"It's easy to guess." Jiang Yao shook his head and denied it, "Because the paint merchant wiped his mouth with a tissue when he drank coffee and then threw it on the ground, this person's expression changed, he frowned, seemed to be a little unhappy, and then bent down to pick up the paper, but he didn't say a word, he still sat there in a muffled voice, I guess he should be a sanitation worker, picking up the paper on the ground is out of professional habits, and because of his profession, he naturally dislikes people who litter." ”

After analyzing the occupation of sanitation workers, it is easy to understand that this person was silent at the beginning, like a deep person, when everyone at a table was chatting and talking, he was silent not because of his stable personality and few words, but because he lived in different circles, he couldn't fit into those topics, and he didn't know what to say to these people.

Jiang Yao could even feel that this person was a little inferior, so when he sat there, he was always watching other people's words and deeds, afraid of saying the wrong thing and doing the wrong thing.

"It's easier to guess if there's one left." Jiang Yao laughed softly when he said this, "The eighteen or nineteen-year-old boy is the youngest of the men at that table, he is sitting next to the sanitation worker, the two are somewhat similar in appearance, you should let me guess that these two are father and son." ”

"But your answer is clearly not." Head Lin continued, "Let's talk about it." ”

"Not only were they not father and son, but they hadn't met before, so they didn't even make eye contact when they sat together. This little boy has a very cheerful personality, he is very skilled in his movements with coffee, he should drink it often, and I noticed that he has made eye contact with the waiter who passed by them many times, and he has a grimace-like expression on his face, and he has also communicated with the cashier at the bar several times with lip language, and it can be seen that he is very familiar with everyone in this café, so he should be the waiter in this café. After Jiang Yao finished speaking, he looked at Head Lin quietly, "I'm done with my analysis." ”

"Why don't you think he's a frequent coffee guest here?" Head Lin asked puzzled.

"The communication and response between colleagues and friends is completely different from the communication and response between old customers and familiar waiters, if he is just a regular customer, those waiters should respond with a smile in the face of his grimace, and the cashier's little girl should not respond to him with a roll of eyes." Just this Jiang Yao was sure that this little boy could not be a regular customer of this café, but could only be a staff member.
