I on the contrary am quite sure as this was suggested to me by a local, who grew up in the area. I just doublechecked with him and he ensured that this is indeed the typical look of a local "maitolaituri" or whatever they call them in these swedish speaking regions. This friend of mine also confirmed that the "booth" never has seen someone selling stuff there.  To me it also looks like you would need to be quite short as well to be able to fit into the booth.
