Stay Cool and Calma
I'm not sure, but it seems like Venezuelans take great pleasure in making things impossibly frustrating for Gringos, then will ignore them completely if they become agitated. Consider this a test of your character; simply smile and ask for more information, stay cool and be polite. Displays of anger at a airline counter, checkout stand, or police station (God forbid) will not be well received, so, stay calm, cool and polite in all situations. By all means do not react in anger or contempt toward a police officer, even if you feel you have been wronged; a perceived insult could really ruin your day!
Politics are not discussed in public
Venezuelans are extremely proud and patriotic about their Country and their heritage. Exercising your rights of free speech about their government or their political system in public is unwelcome and should be avoided. Discretion is a social norm observed by all Venezuelans and political opinions are expressed only in private. As an outsider, your opinions may be even less welcome, unless you are asked, be a good ambassador and keep your opinions to yourself.
Restaurants
In Venezuelan restaurants it is considered impolite to rush patrons, so you will have to signal to your waiter or waitress when you are ready to order and when you are ready to leave. I think you could sit for hours without any attention if you did not signal that you are ready. A simple look at your waiter and the words “La Cuenta por favor”, will bring the bill when you are ready. Keep in mind that a ten percent service fee is usually added to your bill, in most cases and tipping is not expected (though welcome) in this culture. Hint: A up and down wave of the hand means “come here” anything else seems to get no response.
