I worked for Microsoft in the Seattle area for ~6 years in the early 2000s. My wife and I (both US citizens) went up to Richmond and Vancouver, BC every few months to spend a weekend eating great chinese food.
Every single time, the trip into Canada was great ("enjoy your visit!") and the return and US Border Patrol Experience was horrible. I had people try and catch me on whether Kirkland was on the east or west side of Lake Washington; deep grilling on the specific chinese buns we ate; it goes on and on. I don't think I ever made it through with less than five minutes of solid grilling. I never ended up in secondary questioning, but if it weren't for my wife's love of good Chinese food, I certainly wouldn't have made the drive --- just because of that.
