We were boarding at Amsterdam using steps rather than the usual jetty. All the pax were aboard and we were waiting for the last business pax who apparently, was far too superior and busy to board on time with everyone else. He finally appeared from the terminal, stalked across the tarmac whilst still shouting into his phone and then much to our amazement, started going up a spare set of steps that just happened to have been left nearby. As he got to the top of the steps, he realised simultaniously that a; there was no aircraft at the end of them and b; the crew and all the pax sat on the left of the aircraft were laughing at him! Unfortunately, this incident didn't give him any humility but every time he was rude, I just remembered him standing at the top of those steps wondering where the aircraft had gone!
