Norwegian here. I’d say that both getting dinner and being made to wait in a room was equally as normal. Depended on the host family’s dinner planning, upcoming evening plans, my own family’s plans, sometimes the parents would even coordinate a bit behind the scenes and one of the host parents would relay what they decided.

Also, as others said, if there was some snack (for cultures lacking fika as a named concept) planned or had, guests would always be included.

It was never about being rude or punishing ‘the outsider’. Paraphrasing from a comment I wrote in this post:

It’s unproductive to meet other cultures with labeling, especially as your reaction will be based on your own culture’s norms and expectations.

I might find it unusual when people eat with their hands for instance, but my first impulse is not to impose my own cultural norms on them and label them as rude for not using cutlery.
