Tipping Tips

1) If you are sitting at a table and paying cash,tip the waitress when she brings your drinks. I am amazed at the number of people who sit at tables and then don't tip per round. After bringing them upwards of 4 rounds totaling $15 or more they leave a few dollars on the table.
2) A good tip is 20%, not 10%
3) Pay attention to your server. If they take a long time getting your drink,maybe they are busy.
