Virgil;
you went, assessed the situation, gave it a bandaid ( that apparently works, whatever the situation),and are negotiating with the customer as to the ultimate fix.
this happens a lot to me, with the occasional inclusion of the riot act
you have the right to sit in the dark you have the right to zap yourself anything you say can be contracted against youyou know the drill
Of recent times, I will do the above, then bill out the service call & bandaid with a written warning
I did so say it,,,see....If full disclosure is made to the customer, the responibility & liability falls on them , not you. Myself, I have even laid it on the state here ( they have wide shoulders) in this respect
fire..fire..hehehehehe{Bevis&Butthead voice}
