Want to open a coffee shop next to the school, what are your operational suggestions?

Pay attention to attract customers from afternoon to evening. If you deal in soft drinks, you shouldn't drink. The environment is the most important. Can be nostalgic. Don't be too bright. Dim is the best. Put some books on it. It's better to be nostalgic. People can read them at any time. Music is very important. Better not have lyrics. It would be perfect if we could get some old decorations. If the space is wide enough, it can be divided into single rooms. Every single room is different.
