How to treat your server in a restaurant
When your server approaches your table, give them your attention.
Put your cell phone down and take out your earphones if you are wearing them. Smile and wait for the server to speak before you do.
Respond to the server's greeting. The server will probably make a banal comment such as " how are you today? " they are trying to initiate conversation to develop a rapport with you.
