Genuinely love to break up a combat/dungeon-crawl heavy game with some light-hearted day-in-the-life-of gameplay once in a while. Having the DM describe the lazy cat stretched across the alchemist's countertop, while some mischievious pickpocket tries to nick the rogue's enchanted dagger and the knight errant helps an elderly woman cross the street can add a lot of color to a very number-crunchy game. Picking through a flea market of random niche nebulously useful magic items, while a merchant drops hints about the next sidequest, gives you a real adventurer's vibe.
Genuinely hate having long, drawn out arguments over whether the shopkeep would have the principle material component for my most import spells or basic equipment (there's no bat guano, one swayback horse, and only sixteen arrows in a fantasy city of 50,000 people? god damn, dude). Or digging through spreadsheets to figure out how many javelins the local economy can absorb. Or bickering over whether the Charm Person spell gets us in fight with town guards. Genuinely do not want anyone consulting a series of random charts and tables to determine why we can't get a full night's rest in the town's nicest inn.
Please just make this a fun story to enjoy and not a pedantic fight over the future prospective mathematical efficiency of my stat block in the next combat.
Have you really played D&D until you set up a market stall in the middle of town and tried to convince the DM corpsing as a peasant to buy your exotic, all-organic, dungeon-harvested goods?
