Like many of us, natives of Buenos Aires enjoy a highly caffeinated drink occasionally.  It’s not coffee, but is instead called “mate” or “chimarrao”.  Traditionally, there is a gourd cup with a metal straw that has a filter on one end.  The mate is put into the cup and boiling water is added, and then it is shared communally.
 
Yup, everybody from the same cup.  During the pandemic, exceptions were made and people started keeping a spare cup so they could share only between family units.
 
Oh, and it is considered really, really rude to wipe off the straw when the cup is passed to you.
