Tip around 5–10% for standard table service in Indonesia / Bali. On a 50 IDR bill that is 3.50 IDR, for a total of 53.50 IDR.
No service charge on the bill, so around 7% applies.
In practice: Warungs don't add service; rounding up or 5–10% in cash is a nice gesture, not an obligation. Tourist restaurants often add “++”. Drivers 50,000–100,000 IDR for a good day, housekeeping 20,000–50,000 IDR per day, spa 20,000–100,000 IDR.
