I am not sure if you are asking this seriously. Managing a bar is not about talking to customers. A bar (besides the initial capital you might need to open it) is a full-time activity, and you will become an employer, which brings its own additional (after hours) needs, even if you have the best (in the sense of availability) accountant in the world, there will be counting hours of employees, paying suppliers, various bureaucracy, etc.. Even when (if) you are not there you need to be reachable in case of need, essentially it is a 12 hours/day minimum, 7 days a week work, it can only be your main (and only) job. Otherwise you will need 2/3/4 other people as partners and divide the work.
