Dominicans are incredibly fun-loving people. While not stuffy by any means, they do adhere to codes of behavior that are rooted in politeness. It is a very important aspect of Dominican culture. For instance, it is considered impolite to get right down to business with someone, which tends to be the American way. Instead, if you don’t speak Spanish, a nice smile with a buenos días is a good way to start a conversation. If you speak Spanish, you might even venture forth into a small dialogue about something pleasant (like what a nice day it is) before you go into what you are about to ask of them. This is the same for telephone etiquette.
The Spanish words por favor (please) and gracias (thank you) go a long way toward bridging cultures and making new friends. When faced with street or beach vendors, if you’re not interested in what they’re selling, politely say no, gracias. They will try again and again, but just keep a smile and say no, gracias.
Capturing the Dominican culture can be a lot of fun for photographers, but always keep in mind that taking a photo without permission is not respectful. It is culturally acceptable to ask permission first and then offer a tip if they let you. Most young people will be happy to pose and will be very smiley for your photos, but it’s best to ask first.
While Dominican vendors expect you to haggle, already hiking prices up for the challenge, don’t take advantage of it. It is tempting to haggle in flea markets and with vendors for the lowest of the low prices. But just keep in mind that it is their livelihood. Paying a fair price is a respectful thing to do. The same thing goes for the service industries. If you get good service somewhere, let them know you appreciated it and tip well. Ten percent of a bill is considered a generous gratuity.
Dominicans are famous for being very hospitable people. They are excited to show their culture and country to newcomers who want to learn. They don’t mind answering questions at all when asked politely. They might even offer to show you around or help you beyond what you had asked.
The Dominican Republic  is notorious for fantastic music, great festivals, and all-night dancing. It is also famous for rum drinks. However, partying to Dominicans doesn’t mean excessive drunkenness. In fact, it is highly frowned upon.
