I love how the Belchers don't really acknowledge Ron at first, but he's so pleasant and polite, they progressively acknowledge him more than Hugo and with more enthusiasm.
I love how Ron doesn't JUST do health inspection. We see him a couple times later seasons like working / volunteering at the puppet show set and at the food festival where bob entered the burger cooking contest.
He really is an overall cool hardworking morally upright chill dude and side character. Much less dramatic than Hugo but he does still see Hugo as his health inspection partner. Yet he still does the right thing like the greasy rag fire and he thought it was Hugo who could've caused the fire and made Hugo return to apologize meaning he still checks Hugo when he is really in the wrong.
I really like how Ron being there stops Hugo's appearances from just being completely spite-driven, that there's just this incredibly pleasant and nice man who has to work with the most petty and spiteful man ever.
Since the Regular Sized Rudy episode was so well recieved I would love to see a day in the life of Ron and I know the writers could make it hilarious and show Ron in a great light.
Hugo's a health inspector because he has a deep, personal vendetta against Bob in particular and restaurateurs in general, and enforcing fines and closures is a great way to punish them for existing.
Ron's a health inspector because "Health Inspector" is a legitimately important job, and someone's gotta do it.
For some reason I find Ron volunteering at the puppet theater to be the most adorable thing ever. Not sure why it gets me every time when he starts in with "one might want to put a sticker here...or maybe here..." and when he's shooing the "spider" away.
