Lmao why do NPCs always foist their funeral ceremony on our Sims?

Are you playing with NPC ageing on? Because maybe turn it off?
That community lot obviously chose its staff a few generations ago, and you've played long enough that those former Young Adults have aged into Elders from the sounds of things. The game isn't going to replace them until it needs to, which means when they die.

Also, it's kind of realistic, for TS4's reputation as a Millennial Simulator. Retirement? HA! Not in our lifetimes.
