if the numbers didnt add up on one school job and you had to take a hit to get it done due to lack of service availability and had to pay more for labour than costed for would you walk away from that customer even if they are a good paying customer
this wasnt a remote service he dialled it to do a software update and it all went wrong and if i remember right was going to leave it and risk it until some on here made him change his mind and call the keyholder out to fix it
depends how its progd,good practice is unset only with customer permission but a thread a while back where someone dialled into a set system and fck it up leaving the site with no alarm and had to call the keyholder out
