They were stopping cars at the intersection where the road splits to Club O and the Butterfly Farm Wednesday from about 4-6 PM. I made it through because they had another car stopped, but I talked to someone on the beach the next day and he was stopped and asked to blow and he was higher than the allowed 0 and he had his license taken and told when he didn't have cash to pay the fine, to drive down to Simply and get money from the ATM. He did, and came back and paid the 90 Euro fine and got his license back and was sent on his way.
