The federal government's protection concept stipulates that all restaurateurs must record guest data. This means: first name, surname, telephone number, date, time, table number. This data must be kept for 14 days so that any outbreak of the coronavirus can be traced exactly. How is this handled at Migros restaurants? - Is it also possible to identify yourself via the Cumulus card? For example, for a married couple with a joint Cumulus card, is 1 card with the note '2 people' sufficient or can you also register via an app? I would be interested to know.... ;-)
