Or am I just mixing in the wrong circles?
Try the Dutch!
When you are invited for coffee - the hostess will go to the big cabinet in the corner with the 'show glasses' etc - and on the top of that cabinet will be a tin box of cookies - she will take it down and then go around to all the guests and offer - you are to take ONE - after she has gone around she will put the cover on and put the box back on top of the cabinet.
This scene was repeated in probably a dozen different homes,
Or try the Germans!
I stayed with a young Berlin couple once and they banged on my door the first morning at 6 AM! to ask how many brötchen/semmel/sämpylät I wanted for breakfast - they were going downstairs to the bakery to buy them - price about 10-15 pfennig each.
