You know what, macman, your opinion is pretty sick. The poor bulgars have to be treated the best way in your opinion since they are just kids and here you are hijacking the thread and blaming the owner/victim that it was his own fault. If that's your viewpoint, maybe you should consider another occupation! I guess it's also the rape victims fault if they get raped, because their skirt was too short?
As for the value of the fish, my dad works for an insurance company and they always calculate work in as well. So you could try to calculate the costs of your time for tearing it all down, and setting it back up etc.
