Beautiful stones. What happened to you seems to be a widespread practice. For example, in my town, which is small, someone once had the idea of ​​chopping meat into small pieces and threading them onto small, thin wooden sticks, then grilling them over charcoal, or "skewers." He began offering them for sale accompanied by small hallaquitas (small canned food). He was successful, and lines of people formed to buy. But, but, within a few days, there were already "skewer" sellers in many places, and so many proliferated that it was no longer profitable, and they stopped selling them./Hermosas piedras. Lo que te paso parece ser una conducta generalizada. Por ejemplo, en mi ciudad, que es pequeña, una vez una persona se le ocurrió picar carne en trozos pequeños y ensantarlos en varitas de madera, pequeña y delgadas, y luego asarlos a la brasa, o sea "pinchos". Comenzó a ofrerlos para venta acompañados de hallaquitas pequeñas. Tuvo éxito y se le formaban colas de personas para comprarle. Pero, pero, a los pocos días ya había vendedores de ·pincho" en muchos sitios y proliferaron tantos que ya no era rentable y dejaron de venderlos.
