In a restaurant, der Kunde and der Gast can refer to the same person. Kunde focuses on the person as the buyer of a service, for example when paying or making a complaint. Gast, by contrast, emphasizes the person’s stay and the hospitable service they receive; from the restaurant’s perspective, this term is usually more appropriate.

Als Kunde reklamiert Paul einen Fehler auf der Restaurantrechnung.
As a customer, Paul complains about an error on the restaurant bill.
Als Gast wird Paul im Restaurant freundlich an seinen Tisch begleitet.
As a guest, Paul is courteously shown to his table in the restaurant.
