Meaning of quedar en berlina by Lucas Juárez

Stay or be in saloon is an expression that I have heard and used many times in my environment family. Always referred to some external circumstance had caused concern and capsize to someone. Normally opened a more or less extended period in which one was tense, pending news that eliminated any reason for concern or that, in the worst cases, confirmed that something nefarious or favorably had occurred. Up to here my experience personal. In more recent times I have had the opportunity to inform me that the expression may have to do with " sedan " which is an Italian word for our " 34 cherry; and it was the place that was publicly exposed inmates so they suffered public shame and the derision. According to this meaning meet around sedan would be placed on evidence, in shame, subjected to the mockery of others. In any case seem clear that the situation of who is in saloon not is of envy, even in the use metaphorical, that would be today the only possible in a country civilized.
