Worcestershire sauce from the usual 2 big manufacturers (Heinz, Lea & Perrins) contains anchovies/anchovies (as is traditionally the case). It would be cool if it were possible to find a vegan alternative in a Swiss supermarket - so far you search in vain and have to buy online (which is rarely worthwhile for a 200ml bottle).
If Migros were to offer an alternative brand like Sanchon here, it could well expand its vegan portfolio (and have a nice monopoly, hint-hint!).
