Confusion over stand allocation lead to the following conversation with two pilots in orange jets
ATC: "EZY456, change of stand, you're now going to stand 22"
EZY456 "Roger, continuing to stand 22"
...
EZY123: "Ground, EZY123 vacated"
ATC: "EZY123, taxi on A and hold short of B, you were supposed to be going to stand 22, but the company ahead has just stolen that one"
EZY123: "Roger, A and hold short B, and if you could get his name we'll have words in the crew room"
