After choosing the product, a new modal must be displayed informing the customer can choose ketchup to resume the product purchase
In the product summary, there must be a button to allow ketchups to be added into the purchase
The customer can choose up to 2 ketchups without additional charges
After the third selected ketchup, there must be a charge for each one.
Ketchups can only be shown when the customer chooses a hot meal. E.g.: Hamburguer. Ketchup mustn’t be available when the customer chooses only salad.
In the purchase summary, only the charged ketchups must be considered/counted as a product. If the customer has chosen one or two ketchups, they should be considered only modifiers of one product like a hamburguer.
Plastic Bags don’t have specific business rules. They should appear in the same product summary screen and be counted as a product. They are applicable for mobile ordering.
