Where do I have trouble finding my articles? - Unfortunately in many places:
It's the less frequently purchased items with smaller packaging that don't stand out as much:
-- Personal care & cosmetics : (rank 1) because already small packaging units, similar products
-- Pasta ingredients+preserves and
-- ready meals menus and snacks... because groups flow into each other
-- Promotions, because they are sometimes placed separately in a "different zone" for reasons of space
--frozen products... because the right product is often only visible after the door has been opened
in addition, but only for very special items
-- Meat, fish .... because of pork, veal, beef (not always well marked)
-- Dairy products ... the many yogurts and cheeses - if you are looking for something very special
but I don't have this problem with
--baby & children ... you just look through everything
--Bakery, confectionery and baking and
--Fruit & Vegetables ... the aisles are wide and you have a good view of everything, except when too many people meet there to chat ;-)

As a layman, I can only say where I have problems and not how they can be solved, if only because not all sales outlets are set up in the same way and the articles are constantly changing... otherwise I would already be looking for the articles that are difficult to find on the Internet at home and marking them accordingly on the packing slip and adding the storage location.

But now I'm missing a combination of letters and/or numbers to help me reach my destination more quickly. I'm always amazed at how quickly the staff can guide you to your destination via several shelves... but I'd be happy to hear L6, B-right, rack 35 at the bottom.... yes, of course, these "bottom" items are a problem for tall people with knee problems, for example, and vice versa, the "top" items are a problem for short people with neck pain... ;-)
