Indeed, but not as crazy as the US or Asia - but when you ask them, they say that pre-spend isn't mandatory and that they want costumers who love the brand in all its facets.
I go in ups and downs, I spend mostly on RTW, Shoes and Homeware. Jewelry I don't really like and I don't wear it, will consider a watch soon, but yeah this is where my money goes at Hermès. On the side note, I have friends who don't spend as much as I do, in fact their pre-spend is probably less than 5/6K and they still get bag offers, guess it all comes down to the relationship you establish.
Stuttgart and Baden Baden are also well stocked and the SA's are very nice and welcoming. I don't know much about FFM, but I've heard mixed things about it same as Munich.
