Uruguayans are serious about their mate drinking–they take it with them everywhere.
The mate-on-the-go form executed throughout the country is characterized by tucking the thermos under the arm, and then holding the cup and sipping straw in the same hand. (It’s an advanced maneuver, one that Ian is trying to perfect.)
This one-armed technique allows you to have all of your mate necessities at hand, while still leaving an arm free. For instance, at the bus station, with all of the bags that weren’t heavy (that means all suitcases except for ours), the bus driver clutched his mate accoutrement in one hand and loaded bags with the other. You’ve gotta be impressed by that.
Unfortunately, Ian doesn’t really have the right cup for this mobile mate consumption, so we often hear, “ahhh, I burned my hand,” as we walk around Punta del Diablo.
