Even if you don’t want to make it, I’ve never been in a supermarket that doesn’t offer a fresher option. I’ve even been in gas stations that offer what they at least claim is fresh potato salad.
Maybe if you really, really wanted potato salad and you were in a food desert but the corner 7-11 has canned potato salad you might buy it, but I’ve never seen this before in my life.
I don’t get it.
Mayo vs vinegar is kind of an actual debate in germany. The civilised side and the vinegar people are mostly blissfully unaware of each other until they develop righteous hatred for the other salad as soon as they learn of it. I heard the vinegar version is eaten warm, which sounds even worse. I would say both are authentic, but vinegar potato salad is authentically horrible.
Storebought potato salad will also at best get people talking behind your back in germany, no matter which kind.
I love how clearly this second sentence displays which of the two sides you are.
