发现问题：
每天早上都要买排队买早餐赶第一趟公交，经常差一两分钟错过公交
问题根源：
排队买早餐浪费不少时间，买早餐时间长短太不固定，人多得等，扫码付款操作流程费时间。
解决方案：
1.和早餐店老板沟通好时间点取早餐
2.店老板提前打包放好
3.我提前拍照保存付款码
4.走到店的路上已经操作付款差最后一步输入付款码，而不是排队取到早餐才开始扫码付款后离开
5.到店和老板打招呼取早餐完成最后一步付款
6.离开早餐店去公交站赶第一趟公交车
执行方案：
实际操作了一段时间效果还是有的！提前打包没去实现外，排队和扫码支付操作上省了不少时间，店老板已经默契的不用问我今天吃啥，看到我远处来就开始打包了。
优化方案：
和店老板的熟悉程度已经可以达成提前支付一个星期或者更长时间的早餐费，和具体时间点前一两分钟准备打包好我的早餐，我只需经过店取早餐离开即可的程度，考虑是否执行。
Found problems:
Every morning, I have to wait in line for breakfast to catch the first bus. I often miss the bus by a minute or two
Root cause:
Waiting in line to buy breakfast wastes a lot of time. The length of time to buy breakfast is not fixed, and there are too many people waiting.
Solutions:
1. Communicate with the breakfast shop owner about the time to pick up breakfast
The shopkeeper packed and put away in advance
3. I took photos in advance to save the payment code
4. On the way to the store, I have already operated the payment difference and input the payment code in the last step, instead of waiting in line to get the breakfast before scanning the code and leaving
5. Go to the store and say hello to the owner to pick up breakfast and complete the last step of payment
Leave the breakfast shop and go to the bus stop to catch the first bus
Execution plan:
The actual operation of a period of time or some effect! In addition, I saved a lot of time in queuing and scanning code payment operation. The store owner had already tacit understanding and did not need to ask me what to eat today. When I came from afar, I began to pack.
Optimization scheme:
With the familiarity of the store owner, I can pay for breakfast a week or more in advance, and pack my breakfast one or two minutes before the specific time. I just need to go through the store to get breakfast and leave, and consider whether to execute it.
