I think what it is gnu, we so love our pets we daren't refuse treatment or try to reduce the fee, in case they die or suffer. It's an emotional thing. Vets obviously know this, and while it's only fair they be paid for their skills and long period of training and studies, sometimes they're having a laugh, in my opinion.
We're going to try a new little vet's surgery we saw in a slightly less 'posh' area, and ask what their charges are, for future reference. It'll be interesting to compare the two price-scales.
