This gesture you make in a restaurant reveals your social class without you even realizing it.

Anticipating the bill too early: a reflex that spoils the experience.
Many people mentally calculate within minutes: “If I have this + a drink + a dessert… how much will it cost?” There’s nothing wrong with keeping an eye on your budget. But this constant calculation is noticeable and creates a slightly tense atmosphere, as if everything needs to be controlled.
To ease the experience, a simple guideline is all it takes: set an overall budget before you arrive. Once seated, there’s no need to constantly recalculate. Your mind relaxes, and the evening immediately becomes more enjoyable.

The tricky part: the bill and the famous tip.
