I traveled to Mexico a few weeks ago. In my luggage I had two MacBook Pro laptops and an old ThinkPad. To my dismay the people at the airport in Mexico demanded quite a bit of money, telling me that because I had brought more than one laptop I had to pay import taxes. I am a tourist from Europe traveling with three laptops. I begrudgingly paid up. It’s abusive and stupid to demand import taxes in situations both like that in the OP story and like they did from me.
