I guess it all comes down to what your expectation is of friendly. Personally I expect sturn, firm, no bullshit, and an expectation of everyone to comply. I've never had a guard yell at me, arrest me, hit me, etc. As a taxpayer I expect questioning and searchs as the bare minimum.
If you want smiles and lays when you enter Canada, then put a concierge booth after every border check. Otherwise, respect the effort being out into national security, among other things.
And for gods sakes, if they deal with you professionally and quickly, thank them afterwards.
