Trying to get a Saudi Transit visa in Seoul involved 6 trips to the embassy, probably 50 emails, meeting with 2 consuls, and eventually ended up being denied...3 days before departure.

Had to cancel that ticket and eat my Kazakh visa I already paid to have issued. (Surprisingly easy in Seoul to be honest).

Another fun one, was the Bangladesh embassy in Seoul refused to issue visas to foreign passport holders, even if they held Korean residency visas. I was told I need to 'fly to Canada and get the visa there'

Ya, right.
