I get pissed... specially whne i come back to Canada. One time the officer kept asking me all these questions and i was like:

"This is my country, i'm a canadian citizen and have always been a Canadian citizen. I'm returning into my own country and you do not have the power to refuse me. So if you want to search for drugs or undeclared merchandise go ahead but stop asking me stupid questions about where and why i travel so much. There are other people waiting behind me and all you do is keep asking me questions that are irevelant about me coming back home."

He didn't really like that so he got pissy and i asked to talk to his supervisor. I just told him that i did not appreciate being questionned as if i'm a criminal when retuning in my own home country. That i expect that when i try to visite another country. But not my own.
