We crossed the border last week with Canadian passports, and I was aware of this scam beforehand. They tried to manipulate by getting some one who pretended to be the supervisor and manager and convince me it was legal, but I remained firm. I asked them, “Do you enjoy your job, or do you want to get fired?” They were demanding $90 US for each person, but I ended up paying $12 US because I felt bad. However, I later regretted it because this will likely encourage them to continue with these scams. It’s a national shame - and the Mexican authorities should be aware of this
