Yes we do, but there's a bit of nuance to it. Most Dutch people will happily oblige to speak slowly (within reason) if you preface any conversation with a quick "I'm trying to learn Dutch properly", and will appreciate the effort.
Knowing the language will definitely help people fit in better as many conversations amongst the Dutch will still be in Dutch and also most signage and other written texts will obviously also be in Dutch.
