I was at the WU office this morning, one of the little side offices that are connected by passages to the big office on Cordoba, and they had nothing but 1000 peso notes. First the lady asked me if I had change to bring it up to a round 1000, and when I didn't she asked if she could put the other 700-and-some on my Sube card. I readily agreed, of course. I had to shake my head and chuckle, but it was a clever solution.
The lack of change is getting worse week by week, and what few small bills are in circulation are growing really dog-eared. Bills that a merchant would have rejected out of hand 3 years ago, they will now accept and tape back together.
Argentina, my dear, I love you, but...you really need to get your shit together.
