1. Hygiene problem: There may be problems in the hygiene of the self-service kitchen due to the irregular personnel, high frequency of use and great difficulty in cleaning. For example, food may be contaminated, oil fume emission, food storage and other issues.

2. Single dishes: Because the self-service kitchen equipment is relatively simple, it can't support a variety of dishes, and it may also lead to single dishes.

3. Obsolete equipment: The self-service kitchen equipment is aging, which leads to unsmooth use, poor taste of dishes and even affects food safety.

4. Insufficient service: Because there are no actual service personnel in the self-service kitchen, users need to operate the equipment, eat and clean themselves, and sometimes they may face complicated operations, and there is no way to maintain the equipment if there is a problem. The above are just some possible pain points, and the specific problems of college students' self-help kitchen industry will vary according to different schools and situations.
