There is a way to make money, and you can't be too greedy

The company has several swivel chairs broken, which should be caused by people in the seat who are too heavy or frequent left and right shaking caused by tearing as a tray leads to tilting. The seat tray is made of iron, and the other parts are intact, so it is a pity to throw these chairs away directly, so I thought of welding.

When all is said and done, I found a few individual workers in the same city who undertook welding maintenance, called over, added WeChat to each other, sent a picture of the fault, and let them assess the price. They evaluate each as follows:

The first person: 30 yuan a, need to send to the manufacturer of welding.

Second person: 200 yuan a, door-to-door service, this price is more expensive than buying a chair.

Third person: 100 yuan a, door-to-door service

Fourth person: 50 yuan a, door-to-door service

Fifth person: 120 yuan a, door-to-door service

Because in the office building, asked if the property can be in the building welding operation for a long time without a response, he disassembled a chair, found that the tray is a piece of iron plate tearing, welding well, it is inevitable that it will be easier to break. Think of whether you can go to Taobao to check whether the tray is for sale, a check is indeed there, 30 yuan a, there are tools to disassemble to buy their own replacement can be.

Only this one thing found: 1. Beijing labor costs are still very expensive 2. The same thing, different people's cognition is still quite large 3. Courage to explore, many things are still possible to solve by themselves 4. Understand more things when encountering things, and avoid paying excessive unreasonable costs
