Introductions When members of the opposite sex or two women meet it is customary to exchange a single kiss on the right cheek. Men shake hands.
Greetings In Colombia it's polite to greet everyone in the room when entering with a simple 'Buenas Dias' or 'Buenas tardes.' This also applies when approaching someone on the street for directions or information.
Invitations Generally the party making the invitation to a meal will pick up the tab; splitting the bill is not common.
Honorifics Show respect to older members of society by using the honorific don (for men) or doña (for women) before their name.
Drinking When out with friends Colombians usually buy a bottle of liquor and all take shots at the same time rather than sipping at their own glass.
