Polite manners will go very far in this jewel of the Caribbean. When entering a business establishment, always say, 'Bonjour' and 'Merci, au revoir' when departing. Also note that things often run a lot slower in warm climates, so patience is a must. Also, don't expect kowtowing, smiling 'natives'. The Martiniquais are a very proud, dignified people and are often wary of impatient tourists without manners.
Unaccompanied women in tourist and beach areas are likely to experience frequent cat-calling and similar attention from men. A popularly stated reason for this is that there are a greater number of women than men on the island. The best way to deal with unwanted attention is to ignore the attention or firmly state a lack of interest.
