For the most part I will let this article in the Argentina Independent explain but I do have some comments (see below).
But first, since we are visitors here and don’t want to be seen as complainers, that article says it well:
“One of South America’s most electrifying cities, graced with European culture, architecture, atmospheric neighbourhoods and a bustling nightlife. With a variety of parks, museums, fancy restaurants, boutiques and funky bars, this city of porteños offers something for everyone. Not a weird thing many foreigners fall in love with it, you would think…”
Top Five Annoyances in Buenos Aires
#1 This problem is not a severe as what we found in Spain but it is real. If you mistep, it takes a couple of blocks to fully get over it.
#2 It is surprising how long it takes to catch on to this one. Some of it comes in the form of a misty rain, other times it is full fledge drops which can be mistaken for the dreaded bird spillage. The all too common wet spot is a giveaway so you quickly learn to avoid those.
#3 Because of #1 and #2 it is critical to focus your eyes downward, which is helpful for this one since any mishap in this walking city would put you on the sidelines quickly. When new to the city, it’s a challenge to avoid this hazard while viewing the spectacular architecture above you. Brisk walking is a feat of extreme dexterity.
#4 We have not been exposed or disrupted by this and have only witnessed it in Plaza de Mayo (pronounced like masho) where there are always banners present. But I love a good act of civil disobediance and look forward to our first.
#5 This is a problem of the highest magnitude. For our first week it was a total mystery. An inexplicable unavailability. Now we know. We should have noticed these signs. The other day a grocery bill came to 24 pesos, I provided 25 which resulted in a brief but intense mental tug of war. Sell not sell, how badly did I need it, each trying to figure out if the other had a reserve. It is common to get a 50-centavo deduction if the sale is important enough for the shop owner and/or you are a good bluffer. Preparing for a bus ride takes forethought since they only accept monedas.
Are they short on metal, or just want “your” money. Is greed part of it?
No one seems to know the answer. There are several theories. But the problem is not just with tourist. It is a national problem.
