My first one didnt show up for an hour, there’s a lot of factors and one of them is how accessible your bar area is as in imagine spawning an NPC 10 foundations away and them trying to path to the nearest seat in your bar. I have no idea if the spawn rate scales with how many seats you have either, but I was getting like 1 every 30 minutes when I cleaned up the path to my bar (at least 1 foundation wide)
