In my experience too.
My ex-employer was routinely in competition with a German company to supply particular Special Purpose machinery and in much of the Middle East it was always made clear that there was absolutely no chance of securing a sale without "greasing palms". We would always refuse to do so and invariably the response was, "Why not? The German's will", and we always lost the sale to them. I found it odd how our German competitor, who operated under the German equivalent of the Bribery Act, could do that with impunity while we would have ended up in jail
