Couple of items that butlers have either offered me, or that I've personally used in the past:

- Unpacking / packing of suitcase
- Ironing of shirts / suits
- Shoe polishing
- Delivery of tea / afternoon drinks
- Supporting return of a rental car (when traveling internationally)
- Concierge type requests: restaurant suggestions / reservations; spa appointments
