I am sure that CAG is not a major airport with numerous daily operations. With that being said plenty of time for coffee and ciggies. So why would the controllers not advise crews, for a period of time, that the runway is now open for business and the taxi way is just a taxi way? Better yet... why not issue a trigger notam in bold letters that normal operations are in effect?
It's such a shame that a developed country has a third world aviation system.
