10 Rules For Vegetarian festival

This is the week of the Vegetarian Festival in Phuket. There are a number of publications on the history and activities of the festival including the 10 rules. These rules are as follows:

1. Clean your body and your mind during the festival
2. Clean kitchenware and use them separately from others who do not attend Vegetarian festival (or use kitchen utensils for only this festival)
3. Eat food prepared from vegetables and do not consume strong smelling vegetables
4. Wear white clothing during the festival
5. Behave physically and mentally
6. Refrain from eating animal flesh
7. No sex
8. No alcoholic beverages
9. People who are in mourning cannot participate in the festival
10. Pregnant ladies and women with period can eat vegetarian diets, but cannot attend any ritual or visit shrines

All of this got me to thinking, that given the number of followers, a good percentage of the population here; how is business doing in Patong without people drinking or having sex? And what about those places like McDonalds, KFC and Burger King?
