To be fair and objective to Miss Baerbock, it appears to me that she simply chose to go down the tarmac when the plane's ladder was not quite firmly settled on the tarmac/ground. The same group of people (military officer, Indian diplomat) were just awaiting for the full plane's complete stop before they would and could formally welcome her for safety reasons. But of course I could be entirely mistaken and her welcoming party from the host country India was indeed quite lame to put it mildly.The Indian logic might be:
American and Chinese officials = representatives of near-peer powers to the Indian singularity power = recieve them with a slightly lower rank official
German official = colonial administrator of a near-peer power = unworthy of meeting any official of the greatest superpower.
