Yes, Leslie, a very good assessment of him. And now because he is a customer of the bar instead of the bartender, he also has suffered a major "demotion" within the community he is so proud to be a part of, and that is also a cause for jealousy: and he is jealous of Lauren on two counts, for having the job of bartender, as well as for having an intimate, romantic relationship that considering Lauren's youth, is relatively long term and stable. And so far no one has really called Wayne on his being jealous. He had a relationship with Pete, and drove Pete off through his demands, and his jealousy of the time Pete spent being serious about his job at the insurance agency. So unless he is the cock of the walk and has something to wave in other people's faces for them to envy him, he strikes out at those he himself is jealous of.
But - he is also sick, and Lauren cried a lot of bitter tears over Wayne's suffering, too... and since he has been in a state of relative remission, Lauren and others have pushed away that fact about Wayne, and this will come back to haunt them - all of them.
