You necessarily have to bargain at local markets and in private shops, as it will significantly reduce the price of the item. Bargaining is irrelevant in shopping malls and supermarkets. To make it easier to pay you need to stock up a sufficient amount of small denomination bills in advance.
In restaurants and cafes be sure to leave a tip for good service; it will be greatly appreciated. Tip depends on the place; it is usually 10% of the bill. You can leave a small tip for a maid at the hotel, but it should only be given in hand, as attendants would not dare to take money left in the room.
Despite the fact that Hammamet has fairly loose standards of conduct for tourists, you should be attentive to the local culture. Don’t walk around historic areas of the city in low-necked and bright clothes; bright dresses and bathing suits are appropriate only on the beach and at the hotel.
It is inappropriate to appear on streets in an intoxicated state, as it will be regarded as contempt of the local traditions and a gross violation of public order. Don’t eat as you go, as it is considered a sign of bad manners; this should be done only in designated areas.
Fans of photography should be extremely cautious too. You can shoot locals with photo or video camera only with their prior consent; it is prohibited to take pictures of women wearing a yashmak.
