Customs do catch people sneaking undeclared goods in to the country, so they play tax agents. Customs also finds cash, drugs, weapons. They can't check every car / truck coming in, the interview is to weed the good people out--like me--and catch the guy bring 10 handguns in to Toronto (think how much $ those could fetch) its temping sometimes.
When I read about the stuff they find its shocking. Most people have no criminal record--why they can pass in the first place.
Its when their BS morals they start acting mean its BS......"you come all the way to Niagara just to see the falls" some jerk US custom agent in NY state asked me, yea well theirs a little horse racing track in Erie thats nice to go also, was my answer. Customs agent looked so pissed, i got weed arrest in 84 on my sealed record--which they got the power to see it. So jerk is screaming at me if I never ever been arrested, I was saying NO but then changed it to "not that I can recall" nope never arrested, don't recall anything......oh he was so pissed, If i was a Canadian he could had ran my butt in and ban me from the USA....I got hassled coming back in to Canada but after 25 mins I was on my way back to my hotel....
None of their freaken business what I do in my personal life, I go on holiday to relax, sightsee and visit some clubs, all I pretty much say. Which is the truth.
