Dana texts from the counter. A regular wants ten percent off a catering order that's already past due. 'Okay?' Maria is elbow-deep in tomorrow's prep list. She types back yes before she's finished reading the message.

It's the fourth text like this since 9 a.m. A student discount. A friend-of-a-friend discount. A because-the-frosting-cracked discount. Each one took four seconds to answer and felt too small to argue about.

By 4 p.m. Maria has approved every request that reached her phone. Nobody decided the bakery discounts ten percent by default. It just started happening, one yes at a time.

The principle is ego depletion. The capacity for good judgment is a finite resource that burns down over the course of a day, the same way physical stamina does. Every decision Maria makes, including the tiny ones, draws from the same tank she needs later for pricing, hiring, and the supplier contract she has to review at 5 p.m.

Saying no takes more energy than saying yes. Weighing a discount against margin, precedent, and the next three people who will hear about it requires deliberation. Typing yes requires nothing. By the fourth request, Maria isn't choosing to be generous. She's choosing the answer that costs her less energy.

Researchers running trust games found depleted participants extended about $1.30 less trust than people who hadn't been drained by an earlier task, a gap of roughly $4.31 versus $5.64, from DeWall and colleagues' 2014 study. The effect grows sharper in people prone to anxiety, who lose more judgment capacity under the same load, according to the same research. The bakery has no ledger for this. The cost just shows up later, in margins nobody meant to give away.

Discount text arrives → checked against Maria's threshold and past precedent → resolved on the spot if it matches, escalated to Maria if it doesn't → the four routine asks disappear, the one real judgment call remains.

The routing rule isn't invented by a vendor. It's built from decisions Maria already made and would stand behind. Student discounts under 10 percent get approved automatically. Anything past 15 percent, or from a first-time customer, gets sent to her directly. Dana's text about the cracked frosting closes itself out before it ever needs an answer.

What reaches Maria's phone now is the request that doesn't fit anything on the list. A wholesale account asking for a standing 20 percent break. A vendor dispute. Those get her full attention instead of her leftover attention.

Owners using this kind of filter report the same shift. Fewer texts overall, but the ones that arrive get an actual answer instead of a reflex. The judgment she has left at 4 p.m. gets spent on the decision that changes the bakery's numbers instead of the one that's already been made three times that day.
