Members of the Seniorenbeirat were recently out and about as test shoppers in the city districts. From this summer, further test purchases will be carried out regularly.

Businesses that meet the criteria or are able to compensate for any minor weaknesses with particular strengths will receive a certificate for "Senior-friendly service". The award-winning stores can advertise this special service with a large round yellow sticker on the shop window.

The members of the Seniorenbeirat do not initially identify themselves as mystery shoppers. They look for competence, helpfulness, friendliness of the staff, barrier-free shopping or legibility of the price tags on the shelves and on the products.
