My grandmother had one some years ago.
She was about 80 at the time.
She would normally dress up nicely for an occasion, but on normal days she didn't care much what she wore.
This time she was working in the garden when she decided that she wanted a new pair of shoes. She always wore clogs in the garden.
Obviously she wanted the shoes right now because she went to town without changing her clothes or foodwear, so she probably looked a sight/(fright).
Due to needing a very small size she couldn't get shoes just anywhere, so she went to a fancy shoe shop in the middle of Copenhagen where she knew they had a good selection of shoes in small sizes.
The person working in the shop was being condescending and my grandmother got so miffed that when she decided on a pair of shoes she asked for one in each colour....
( Luckily they only had 3 colours and my grandmother always said that was money well spent just to see the look on the shop person's face )
