Can blasts be substituted for drinks in a combo?

In the context of combo meals, the correct understanding is that blasts can be substituted for drinks, but this usually incurs an additional cost. This means that while customers have the flexibility to choose blasts in place of drinks in their combo, they should expect to pay a different price—generally higher—due to the nature of the items being exchanged. Blasts, likely seen as premium options, warrant this difference as part of the menu pricing structure, reflecting the cost of ingredients and preparation.

The other choices do not accurately capture this exchange's nature. Customers cannot substitute blasts without a price change since that would undermine the value of the more expensive item. Likewise, stating "only sometimes" inaccurately reflects the consistent policy regarding substitutions. Lastly, claiming that blasts can never be substituted overlooks the option itself, which is offered but with the monetary consideration.
