We only happen to know about the incident in Crimea last week because a few outraged Ukrainian officials have chosen to make an issue of it.
"Rather than rush to a meeting, a stop was made to drink a glass with bikers.… In my opinion, it is a diplomatic slap in the face or just plain rudeness. This is a manifestation of abnormal relations," former Foreign Minister Volodymyr Ogryzko told a press conference in Kiev last Friday.
"President Putin exceeded the limits of a delay. He went to meet with motorheads and their friends, showing his priorities," in Ukraine, Emergency Situations Minister Viktor Baloga wrote on his Facebook page, according to AFP.
Last month, at the start of an important state visit to Israel, Putin kept "the entire upper echelons of Israel's government" waiting for 90 minutes before showing up to take part in the unveiling of a monument to Soviet Red Army sacrifices in World War II, according to Haaretz.
