propina = tip, gratuity
A fee? Or maybe a tip? Depends on the context.
Tip
If by tip you mean an amount of money we say: propina. If by tip you mean a piece of advice we say: pauta.
The term "tipping" can have a number of meanings. One meaning is to cause something to fall over. Another meaning is to give a service worker additional money above the amount billed to thank them for their service.
A tip or gratuity is an amount of money that is given to a worker such as a waiter or waitress who performs a service for you.
a tip A bonus
* 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.
A discount is money off a product, a sales tax is money added to the price of a product, and a tip is money given to someone fr good service.
A service tip is simply called a 'tip' or 'gratuity' and one pays a waitress; waiter; bell boy in a hotel, etc., if their service is good. A service tip is generally 15% of the total bill, but can be less. If the service is poor then one can decide not to leave a tip.
- the extremity or pointed end (tip of the fingers for instance): le bout (masc.)- a hint or idea: un indice (masc.)- a small amount of money given to a waiter: un pourboire (masc.) (in mainland France tipping is falling out of use as service is included in bills)
Tipping is usually based on service. The standard is 20% for good service. If the service is excellent, one could tip 25%. But, if the service was poor, one may choose to tip less or even not leave a tip at all.
It is always customary to leave a tip based on the original price. The person receiving the tip should not receive less money for a service that could have cost more without a coupon.
