I think you touched upon it in your last paragraph acknowledging being white and kiwi.
It is such an overwhelming force of human friendliness and welcomeness, that you assume it must be genuine human connection.
Except try being gay, black, or an atheist, and see how quickly all that turns...
As far as the rest of your points, I think you're exaggerating a bit. Most people (at least in north america) don't mind being micro-friendly as part of a service job. Sure, yes, it's "required", but the ratio of monstrous leering arseholes is not high, and while it's tiring to be friendly by the end of a long workday at a grocery store, people don't feel it to be a fundamentally dehumanizing act.
I think the bigger problem with tipping is situations where it allows employers to pay less than minimum wage - that is abhorent. Getting a tip shouldn't be a requirement to get to a living wage. But as an incentive to being a little more engaged with your job? I think it's good.
> Edit: in my experience Canadians and New Zealanders have similar outlooks.
We are alike in many ways. We both live in the shadow of a larger, brasher arrogant power who dismisses us, and people on the other side of the world lump us in together with them.
But no, when it comes to restaurants, service culture, tipping, and micro-friendliness in public Canadians are much closer to Americans than to New Zealanders.
