BBQ's are a great tool for management to increase morale. I'm sure all the management staff will feel the warm glow of (self) appreciation as they gobble down their snags while everyone else is too busy actually working to turn up. Although I guess those with a day off could come in to the airport to share the love...
I believe management have been gobbling down snags for some time !!
Perhaps the BBQ's will climax with the engineers dressed up as the Qantas choir singing 'I Still Call Australia Home' and then have a nice refreshing popsicle or six to complete the love fest !
