Incidentals like F&B, spa and others count towards points (see Wiki for full list of what doesn't count). You have to look at the bill carefully and not include the service charge and taxes. Whatever the amount is in USD you multiply by 10 and that's your base point total. Then add 25% for your Gold status. If in doubt, next time ask at checkout for them to highlight which items are applicable and they can work out a rough total for you.
