It’s still better to hear this lying message and then be kicked off than when they have you talk to the robot that tries to understand what you want but can’t and then ends up telling you what movies are playing right now in Singapore for some reason.
So the length of the queue is the expected average, right? Then, if you fall off that you are therefore the above average call in the message… except the length of the queue probably doesn’t actually much to do with any kind of average of the number of calls.
