If you leave additional money on the table, you’re tipping twice! Leaving a few euros for a particularly great meal/great service is always appreciated but never expected. If you decide to tip, just leave the coins in the plastic tray with the receipt on the table. It’s perfectly fine to round a bill up if you had good service like leaving 40euros if the bill was 37 euros. You can go a little higher at a particularly fancy restaurant where you had a wonderful meal. But it would be unusual to leave a 20%, USA style tip at a mediocre casual restaurant, so don’t do that unless you really feel compelled for some reason. The tip you leave is called a pourboire which is just the amount the server can use to purchase a drink for himself or herself. If you choose not to leave a tip that is perfectly OK too![/quote]
