Taxi Scam?

Leaving the Lucha Libre event last night I saw a cab driver and asked him to take me to my destination. He said sure and directed me toward his car. Iasked him how much it would cost to go there and he kind of mumbled something about “it it’s fine. He can get me there” its was close… So i asked again how much and we agreed on 100 pesos. when I arrived, he said that it was 100 pesos, but it was credit card only. Luckily, I had 100 peso dollar bill. I was trying to hand him and he had this little plastic skimmer looking thing he wanted to swipe my card with, I said I’m not giving you my card and put the hundred peso bill on his seat and walked away. Glad I insisted on the amount before hand. 👌
