Went to Paloquemao market on Saturday looking for queso costeño. Asked the price (15,000 COP, full block). Smiled, said "ay no, está caro, ¿no me lo deja en 12?" The vendor laughed, said "para ti, 13," and we shook on it.

I felt like a local for exactly 8 seconds. Then I realized I was still paying in pesos using a credit card from a US bank speaking English-flavored Spanish. The 8 seconds were great.
