They ask for the documents, which they didn't mention in the must carry documents list.
It's a shame, even if you have an appointment,"first-come first-served" if you have an appointment at 09:45am and an other person at 10:30am, if this person will arrive at the Embassy at 09:30 and you at 09:35, the other person will be served first. So why the appointment? And the most forms of shaming is that you have to wait your turn outside of the Embassy, even if its raining, snowing or "minus 10 celsius" outside.
Mister Ambassador, change your rules for appointments please, and give the people who wants to visit your country and apply for a Visa, a confort place (Space) for waiting. This morning I had the feeling to be on a demonstration in front of the Embassy instead to apply for a Visa. For me, this is an profound form of shaming and arrogance against people.
