I walked to finisterre with my last overnight stop being the municipal in Dumbria. When arriving in Finisterre albergue they looked at the stamps, looked at us and asked with a huge questionmark: did you really sleep there last night? Euh yes we did. Its not the normal way, but yes.
It wasnt that they didn't believe us (i asume), but apparently they had never seen anybody take that detour before. We then got our finisterre compostella and a bed
In muxia the next day the only thing they looked at was the stamp from Lires and then we got the muxiana. They did not even look at us. Hmmm.
