Translation of manchar

for a minute I blamed the burger that I had eaten at the duty free back in Cancun, but thinking a little further I recalled eating street food the night earlier, as it was Mexican independence day.
I still needed to get to the traveler's agent nearby to book my flight back to Cancun. I gave myself two more days to stay in the region, as I wanted to make sure that the hurricane was over.
By the way, after my horrible experience I had changed the hostel. The place was not really better but much more quiet and near the Ocean. I woke up with the sound of a siren. It was the police.
