Not OP, but I live in Munich and have heard of both six-week and one-day waiting times this summer. It depends on part availability. One day is common, six weeks not unheard of. A friend waited almost that long when two strange and unusual screws had to be replaced, the wrong ones arrived from the manufacturer, etc. The quick routine procedures failed her, the result was slow.

Just from what I hear, it seems that there are more cases of unavailble parts this summer than a few years ago. Maybe the supply chains haven't quite settled after covid, even now.

The person who mentioned six weeks didn't specify whether Van Moof has a six-week average or whether it's a 99th percentile.

It was claimed six weeks was common, common is more like 'average' than it is to '99th percentile'. Your example of the missing screws is unfortunate but it also sounds like something that is not 'common'.

Right. Old and unusual screws, a misunderstanding on the phone, someone on vacation... it was an uncommon congregation of bad luck.

Words like "common" have stretchable meanings, though, and particularly on Twitter.
