tip
* Every restaurant is different. Sometimes when you leave a tip the money from all waitress' or waiters are pooled and divided (bus boys may get some of the tip money as well.) With other waitress' and waiters they may be able to keep the tip for themselves. Generally you tip a waiter 15 percent if the service is good. If you don't feel within reason you have had good service you do not have to leave a tip.

crown, tip,
"un pourboire" You don't give the tip when ordering, you leave it on the table with the bill when you are departing - assuming you are pleased with the waiter. Tips are less and less in fashion as the waiters' salaries are already included in the bill (line "service")
Giving commission to waiters in SA is not compulsory, but it is considered good manners to tip 10% of your food bill, if the service you received was satisfactory. If not, you do not have to give a tip. Some restaurant do include a 10% commission in the bill and then you do not have to pay anything extra.
No. In the United States, the only workers who are tipped are waiters, bartenders, and baristas, generally. If you see a tip jar at another kind of establishment, you could drop some money in it if you wanted to, but it is not required. Generally retail workers (which is what Autozone is, a retailer) are not tipped and, in fact, the workers might get in trouble if they accepted a tip from you.
Waiters should not have to tip other tipped employees. Those employees have to work together. Usually they will split things up, they should work as a team. Waiters should tip out busboys 10% of the tips made that shift. Waiters should tip out the bartender less because a bartender usually makes as much, or more than the waiter does. It is common to tip a bartender according to the amount of mixed drinks they have to make. If you had a busy night, but did not order very much booze, than usually the bartender is cool. But if you have a busy night and order alot of mixed drinks, than you better pay the bartender half of what you give the busser. Bussers should be tipped out everynight.
