Instead of THE GUBBMINT being evil by LOCKING EVERYTHING DOWN in some scary QUARANTINE ZONE or the like, imagine a “got to build up zombie bite immunity” response, or one with pseudoscientific treatments, or pretty much anything so 
can feel like things are back to normal while zombies are just a thing that continues happening.
Add your own ideas if you like. 
It’d need a Golden Corral scene, maybe where the chocolate fountain is made slightly more gross because zombie movies are edgy like that, and
dips in anyway after taking some horse paste or something, maybe even taking a smug up-the-nose selfie afterward in the parking lot to send to his 
to stick it to the wokes that are too scared to enjoy things, and immediately afterward, he violently thrashes and goes 
in the cabin of his F-150 and no one notices because it’s only a slight behavior change for him.
A movie where the zombified boomer chud is the main character, and acts like a classic violent, mindless, bloodthirsty classic movie zombie, and the only change that people around him notice is that he’s slightly less awful to be around than usual.
“Dad hasn’t said something racist in like 3 whole days… Is something wrong?”
“Yeah I dunno, he didn’t even grab his gun before answering the door today.”
