It's a bit silly as a complaint..I mean nobody was stranded, nobody was delayed, it was a minor thing that led to a very minor inconvenience for the OP.

The vibe from the OP seems to be that he felt it to be a slight against his country's passport which I assume is Swedish or Finnish that the gate agent had to check it again. That would seem quite unlikely and more based on a misunderstanding of procedure on part of the OP and as a result the entire thread is a bit petty.
