Many cards in Agricola give you bonus resources under certain circumstances. For example, the Stone Carrier occupation says:
Whenever you take Stone with an action, you can also take 1 additional Stone. If you also receive other building resources, this costs you 1 Food.
Many cards also modify existing actions. For example, the Quarry reads:
Whenever you use the "Day Laborer" Action, you receive an additional 3 Stone.
If you have a Quarry and a Stone Carrier, and you take Day Labour, do you receive 2 food and 4 stone?
Is this generally true for all cards that supply bonuses?
