I have two sewing machines in need of repair - they are heavy, and I can't lug them around. So I phoned three service shops asking for a house call, and all three gleefully informed me that they do NOT make them. Service only in their shop, at their convenience, or none at all. I asked if anyone would condescend to come after business hours - no dice. Then, would any mechanic be interested in a little side business? No way.,,,! Amazing, as one of these shops is six blocks from my home, and another just five minutes away.
That exemplifies the way merchants act in Argentina. First come their personal convenience, and in 35th. place, the customer's needs. Now, I don't think these shops are swamped with customers, what with being January and people watching every penny. Yet, those merchants refused to change their way of doing business, i.e.: customers be damned. It is clear that they've never heard of Darwin - species that don't evolve and adapt will go under. Same for these shops, I'm afraid.
Giving up, I resorted to MercadoLibre where I found an enterprising guy willing to come all the way from Caballito. He's the hope for a new Argentina - may his descendants multiply and people this poor, God-forsaken country......!
