Sounds like it might have been in Germany? DUS used to have this procedure until a couple of years ago and I think HAJ still does.
As you say, a bit 'different' but works well.

What a tragic story. Do you mean that the poor pilot made some sort of error and was jumped on by others on the freq? He must have had some extra problems at home as well if he felt so bad that he hanged himself later. So sad.
To come back to the incident at DUB; my experience is that it can get busy and a tad confusing with unusual push-back procedures and ground markings, as well as quite lengthy taxi clearances. Couple this with a few missed calls and double transmissions and it's no surprise that there is the odd 'event' that needs trapping. I haven't listened to the recording but I wonder what was going through the minds of the pilots who felt compelled to add their tuppeny-worth - did they really think that they were contributing anything useful? If not, it's normally a good idea to just shut up, especially on a busy frequency.
