If the restaurant offers Combo and allows guest to change item in Combo, the manager needs to create multiple combos equivalent to the number of changeable items.
For example:
- The restaurant sells Combo includes 1 roasted chicken with pepper + 1 Coca Cola or 1 Pepsi.
- The manager should create 2 Combos: 1 roasted chicken with pepper + 1 Coca Cola and roasted chicken with pepper + 1 Pepsi.
By creating 2 combos, the waitstaff can quickly select combo instead of changing item.
