Opening a part-time snack bar can be written on your resume, which is a positive experience and can show your entrepreneurial spirit, management ability and business acumen. Your resume can briefly introduce your store, including the types of goods you operate, target customer groups, marketing strategies, etc. And your role in this process, such as store management, financial management, marketing and so on.

It should be noted that if your experience in opening a part-time snack bar is not directly related to the position you are applying for, you can consider putting it in other parts of your resume, such as "personal experience" or "hobbies", which can better show your personal abilities and characteristics. At the same time, you can also introduce your experience in detail in the interview, so as to better show your ability and potential to the employer.
