One should not stop him, even though the glass may be full. Toasting wine, presented after the conclusion of the meal will be placed on the table. Members of the mess serve the toasting wine themselves. When serving the toasting wine, members should always pass from left to right. A toast is the traditional and formal way of honoring a country, organization or institution.
Formal toasts are never drunk to individual persons by name.
At about the same time that the port wine is placed on the table, the ashtrays will be placed. One should not drink the port, nor smoke. The important thing to remember when passing port is that the bottle must never rest on the table until the last glass at the individual table is charged, and that each glass is charged whether the member drinks or not. As the bottles are emptied, the member having an empty bottle will raise it to indicate that a replacement is needed. When a bottle has reached the end of the table and the last glass is charged, it may be set down.
