It's said that in Canada, many people in traditional service trades have questionable honesty. For instances, car mechanics, building repair people, and financial advisers (read, financial salesmen).

And we often hear journalists cry out "buyers beware".

But, it still may be the case that the numbers of good people in those trades far exceed that of their corrupt peers.

Any biz deal is an exchange of biz values and economic values. You've got to accept it, warts and all.
