We have a customer who is a single elderly man. He is working in a shoe factory nearby. He always buys some sterwed pork head meat for 15 yuan. Then buys two steamed buns and two bottles of coco cole. That's his dinner.
He is about 55 years old but always alone with himself. He is always hunched over. He is shy and social anxiety disorder. He is always alone. It seems that he has no friend no relative no children. He never pays with his phone. I even didn't see his mobile phone.
He is afraid of the crowded group. If there are over 5 people in our shop. He will galance inside and go away. Afer 10 to 20 minutes later, he will come back if there are few people inside.
We didn't see him for a long time. He came back again today. But he is obviouly weak and shin than before. After talking with each other, He told us he is ill. At that time ,many customers came in. He went away at once.
Anyway, I hope he will be better soon.
