A few things to keep in mind when visiting Egypt : Though Arabic is the national language, most people in the tourist industry speak English and other European languages. Most signs are offered in both Arabic and English.
Egyptians have strong feelings toward alcohol consumption. Most don’t drink at all, and consider public drunkenness offensive. You can find liquor at many restaurants, bars, and hotels, as well as some specialized stores in upscale neighborhoods. But be discreet, and don’t count on finding any alcohol during the month of Ramadan and other religious holidays. Smoking, however, is widely accepted, and you can smoke almost anywhere. The only exception would be if you see a no-smoking sign.
If you are in need of a restroom, stick to restaurants and hotels, if possible. Public bathrooms are usually dirty and rarely offer toilet paper. In fact, it’s not a bad idea to carry your own toilet tissue at all times. Bathrooms are clearly marked for men and women, with international symbols or M for men and Mme. or Mlle. for women.
Tipping, called baksheesh, is accepted and expected. In general, leave 10% to 15% at restaurants and bars, even when service is already included. At upscale hotels, you can tip the luggage porter, doorman, and chambermaid, as well, anywhere from LE 2 – 10 each. You can also tip about LE 1 - 5 for various doormen, valets, porters, and bathroom attendants. It’s not necessary to tip cab drivers, and best not to hand out money to child beggars.
In terms of attire, women are safest wearing skirts or pants that come below the knee, and sleeves that cover the shoulders. Men should also have their shoulders covered, and wear long pants. (Shorts and tank tops are okay on the beach.) In mosques, women need to cover their hair, and everyone needs to remove their shoes.
