Bolivian Spanish word
la yapa
Meaning: a little extra a vendor adds for free
How it is used in Bolivia
The pueblo mercado runs on relationships, not prices, a casera who's known doña Nati for decades adds the yapa unasked.
Relationship currency, not a discount, thanked warmly by name, and never, ever requested.
The small extra a casera slips in for a good customer, a handful more, a little something free. Asking '¿y mi yapita?' with a smile is warm and expected, never rude; it's a sign of the relationship. Because it's a gift, it's received with thanks, never demanded.
