Food server/bartender jobs come to mind. Not only do you meet a lot of people but they often are repeat customers. People would rather hire someone they are familiar with than a stranger off the street and it helps if they see you have a good work ethic. If you are like me and don’t have a college degree don’t underestimate qualities you may have that will work for you. Just by showing up with a positive attitude and being trustworthy puts you ahead. Every job I’ve had in adulthood came by word of mouth and they have all been small businesses. The job I wouldn’t recommend is a factory job. They often will pay a couple of bucks more and seem ideal if you don’t want to deal with the public but you won’t meet many people besides your coworkers unless you work the dock. I hope this helps, good luck
