Worst US/Canadian border crossing

Long time ago my buddy and I used to make beer runs to Sarnia for our couple cases of good Canadian beer. Never usually an issue but one time we were invited to go inside while they looked over my truck. Was asked the usual questions and to hand over our drivers licenses while the nice agent went into an office with a one way mirror so he could observe if we got a bit nervous or something. Asked how much money we had with us and to show him our wallets. They ran the dog over the truck and looked in the usual smuggling places. Heck, all we wanted was some beer, THEIR beer. While there we saw a young fella and his girl led into separate rooms. One agent in the office said they were invited in for a body search. After about 20 minutes we were politely told to get the hell out of their office.
