What should you do if a customer is lactose intolerant?

The most appropriate response to a lactose-intolerant customer is to offer them lactose-free ice cream. This option specifically addresses the dietary needs of the customer, allowing them to enjoy a treat without experiencing discomfort due to lactose.

While sorbet may be a suitable alternative for customers avoiding dairy, lactose-free ice cream is specifically formulated to provide the ice cream experience without the lactose—making it an inclusive option for those with lactose intolerance.

Regarding the other suggested actions, washing and sanitizing equipment and opening a new bucket may not directly cater to the needs of the customer seeking a lactose-free product. Informing them about available dairy options does not help their lactose intolerance, as these products are still dairy-based. Overall, the best approach is to provide a suitable product that allows the customer to enjoy their dessert safely.
