 *   - Restaurant receives: Subtotal - 5% Payfrit fee + tax + tip
 *   - Payfrit receives: 10% of subtotal (5% from customer + 5% from restaurant)
 *
 * POST: {
 *   BusinessID: int,
 *   OrderID: int,
 *   Subtotal: number (order subtotal in dollars, before fees),
 *   Tax: number (tax amount in dollars),
 *   Tip: number (optional, in dollars),
