You'll need to offer a different tip depending on the service provided. Add 5% to 10% extra onto the tip already included in the bill at a restaurant. At a hotel, tip the housekeeper $1 per day and the porter $1 per bag. Tip the concierge $10 to $20 per service. Tip cab drivers 10% to 15% and guides $20 per day. The tip amount will vary depending on where and who you're tipping. At restaurants, add a shekel per customer to the tip already included in the bill. At a hotel, give a shekel or two when asking for a small favor. Porters get six shekels per bag, and housekeepers get three to six shekels per day. Taxi drivers should get 10% to 15% and tour guides should receive 90 to 120 shekels per person per day. Tour guides who also act as drivers get 120 to 150 shekels. As with most countries, tip amount varies depending on the service provided. Tips are not included in the bill at restaurants here, so you should tip 10% to 15% of your bill. At hotels, offer the concierge $20 to $25 when you first arrive. Porters receive $1 to $2 per bag, and housekeepers receive $2 per day. Guides should get a tip of $10 per person per day for individual tours and small groups, or $7 per person per day for large groups. Drivers should get $5 per person per day, and a driver's assistant should get $2 per person per day.

Summarize the following:
The manufacturer should provide directions for use and information about how to store and consume your supplement. Your supplement will probably be a small tablet or capsule that you need to take with water. The instructions label might also feature a chart that provides information about how often to take the supplement. Your doctor's instructions and knowledge of your own health should supersede any recommended intake advice provided by the CLA manufacturer. There are a number of side effects associated with CLA supplements. These mostly include flu-like symptoms such as watery stools, vomiting, nausea, and general lethargy and fatigue. You might also experience headaches, dizziness, constipation, and/or hives (a kind of rash in the form of small, red bumps on the skin). Clinical symptoms include higher levels of cholesterol, an enlarged liver and/or spleen, increased risk for diabetes, and reduced nutritional value in breast milk. Most people report that the side effects subside after about two weeks of regular use. Some people believe that supplements are an acceptable alternative to medication. However, medications receive far more testing and evaluation than do unregulated supplements like CLA. Medications are prescribed by a doctor, and carefully dosed in order to provide you with the right amount. CLA supplements cannot substitute for doctor-prescribed medications. CLA supplements come in different concentrations. Some supplements are 500 milligram (mg) tablets, others are 1,000 mg tablets. Research suggests that the average person needs no more than 3-4 grams of CLA per day. So if your supplement is 1,000 mg, you could take it three times per day and meet your daily CLA intake goal.
summary: Always follow your doctor's advice and consult manufacturer directions. Look for side effects. Don't take CLA supplements instead of medication. Don't take too much.
