Many restaurants now only offer reservations with time slots. For restaurateurs, this is an opportunity to serve more customers – often a nuisance for guests.

In New York, Los Angeles, San Francisco, London, Paris, Copenhagen and Stockholm, tables are sometimes occupied up to three times in one evening. Time slots for reservations in restaurants are "legally unobjectionable," explains Julia Zeller, a lawyer at the Bavarian Consumer Center. But it remains to be questioned whether the time frame is conducive to satisfaction and, above all, the cosiness of a restaurant visit.
