@Walter Hinteler,
In my wife's native region, people can shop at both Aldi-chains (South and North), because it's just the border.
We here think, Aldi-South to be better, while people in the southern regions would like to shop at Aldi-North. (USA is Aldi-South as is the UK)
Aldi split in 1961 .... because the two brothers were at odds, if cigarettes and tobacco should be sold or not. (Aldi's cigarettes are manufactured by
Austria Tobacco, a division of
JTI - Japan Tobacco International .)
