I try to only pay cash in CR. And if I have to use an ATM in CR, and even card readers here in the US(like in the gas station), I always check with my finger to see if a "reader" is inserted.
And I agree with Orange, a credit card in a 3rd world strip club? no way.....especially those clip joints. They are outright overt about their scams; drink padding, BS dance counts, chica drinks at $20 per, taxi driver commissions, etc. Elite & Tango India are notorious. I have had arguments just to get out of those places. You have to watch your bill more than watching the choices

They are super super hot though. Real stunners.
