Its not nice to be "pointing fingers", adding more fuel to fire, and witch hunting.
Like any industry, its tough in Singapore. That's why you have lots of monkeys to go with the peanut food.
Let me ask you, (if you drive). Do you like taxi drivers?? The most likely answer is that they are all the suckiest drivers around. But the truth is that a bunch of rotten apples make the whole basket look bad.
Same with sound engineers. The hours long, the hauling tough, the mental aganoizing, the money??? Let just say well paid engineers are scarce.
Being an sound tech myself, I have seen many peers with no feel for the job, poor technical knowledge, some with a bad temper to boot too.
But does not mean that all are like that. I know quite a few who are so dedicated to their profession that they personnally take care even the small details that stage crews leave out. Running from board to stage, and back umpteen times.
Let me share a personal experience which you can try.
I went to setup for a show to just supply the K-ok playback system, and to patch the other supplier sound system. This is the instruction from the organiser.
Upon setup, they told me that their contract does not include the patch in and they won't let me patch to their system.
So I ask them to check with their boss, to confirm. Which they did.
Rather than to argue with them, I bring this matter to the next level. The organiser to let them sort it out.
The organiser then tried to reason with them, but to no avail. They stood fast. All this while time ticking away.
Then I tell the organiser that if they wanted to K-ok on, I would charge a norminal extra to bring in my own set of speakers and mics.
The organiser relented, and I brought in my stuffs and set it up along side with the other supplier. End up they only used their system for the GOH speech. And there were 2 seperate systems there, damm funny.
In the end, the organiser was extremely pissed off with the other supplier stiff ways.
Moral of the story, no use to get into a fight fest. If reasoning with the same level fail, bring in the next level of management to sort it out. Like that you don't look bad either way as you have gone by the proper channel.
