Best WiFi password for restaurants

Today I went to a Restaurant. I saw there is WiFi service. So I ask for the password. The waitress told me eat first.

So I place my orders.

After eating I asked again for the password and again she told me eat first.

Feeling frustrated, again I order black Coffee. After drinking again I asked for the password. They told me eat first.

Then angrily I asked the Restaurant Manager for the password. He replied eat first.

Before I was about to explode, I finally saw a sign showing WiFi  password “EAT FIRST”.
