I don’t know anything about running a business like a coffee shop but yk instead of taking classes I’m not saying you shouldn’t what you should is ….. heje ena sit on other coffee shops and see how many people come in on different locations how they do the business….. tell them your conducting a study from a college mnamn keza take time to physically learn( ask about the indoor jobs) how it’s done from different locations…. Taking courses wouldn’t be bad but it’s not gonna help you learn how the actual groundwork is done on your specific sector…… I hope this may come as a help to you. Good luck !
