A large storefront is well-equipped, with many employees who work together and are capable. It is standardized in all aspects. You can learn a lot of management systems and organizational skills when you go in, and your promotion is a little slower, but there are also more opportunities.
There are few people in the small shop, and the boss may be the superior. When you go in, you may do everything, such as purchasing goods, registering cashiers, receiving customers, etc. If you are diligent enough, you can learn a lot of practical experience, because the strength of the small shop is weak, and there must be some sales experience in the face of cruel market competition.
finally, I wish you success!
