Do you and the other shopper share a language? If so, it should be easy. If not, use an app like Google Translate, but be warned that the translations are not perfect, and try as hard as possible to avoid idioms. For instance, "hit a home run" has no viable translation into Spanish (that is the opinion of a Professor of Spanish and several native speakers of Spanish who are fluent in English).
