-### Entry fee handling
-
-Festival entry is flexible (10–30 €, sometimes paid as overpayment on drink tab). Options brainstormed:
-
-- **A. Implicit overpayment** — pre-fill pay form with `open_balance + 20`, treat anything above drinks as entry/donation. Zero schema change.
-- **B. Quick-pick suggestions** — pay page offers buttons: `Nur Getränke (X €)`, `+10`, `+20`, `+30`, plus free-form. Recommended.
-- **C. Explicit split** — separate entry field/checkbox. More UI, more accurate stats (`entry = paid − consumed`), more friction.
-
-Lean B. Stats can later derive entry as `paid − consumed_drinks_price` per user.
-
 ### Pay-on-the-spot / quick-pay-cash
 
 Single button on `me` (and crew_user) page: "Offenen Betrag bar bezahlen" → creates `UserPayment(method=cash, amount=open_balance)`. Lets bar crew clear tab in one tap when guest pays cash directly. (Skipped for now, keep in mind.)
 
-### Round to nearest 10 €
-
-When pre-filling pay amount or showing quick-pick buttons, optionally round up to nearest multiple of 10 €. E.g. drinks 26.50 € → suggest 30, 40, 50. Easier cash handling, implicit donation/entry.

 ### Prepay vs. pay-at-end
 
 Currently a single open balance. Could surface "Prepay 50 €" as a flow vs. "Pay at the end" — same data model, different framing. Maybe a "Vorkasse" preset on pay page.
