In Scarface, Tony and his crew are sent by Omar on a deal with Colombians. That deal didn't end well for both Hector and Tony's crews. But I don't understand what went wrong.
With Omar's connections and Frank's money, Tony is supposed to buy Hector's cocaine. Tony doesn't seem to have funny businesses in mind, just wants to make the deal. Hower, the Colombians quickly freak out. I don't understand why Hector suspects something on Tony. As a professional drug dealer, Hector knows that no one would simply come waving the money before checking if the deal is legit, but he seems to blame Tony for his cautiousness.
Also, the Colombians had the drug, so they intend to make the deal, so why did it end that way?
