He is a really down on his luck guy. A single dad with two Krabby kids, struggling to meet ends meet, where life has just been extra hard for him lately. Now being out of a job, he got some help from the UU pokemon to work at this bar, for which he is eternally grateful for them for helping him get back on his feet somewhat (except Haunter, FUCK Haunter. He just gives him a really hard time for no reason). 
He is a pretty chill, if melancholic and tired guy, who does his job well.
