>I understand that in many social organizations, such as the Worshipful Company of Fishmongers, Masonic Lodges, etc., there is a regular order of toasts at a formal dinner. The first is always the "Loyal Toast", to the Queen; and there is a strict rule which goes that "smoking is not permitted until the Queen is drunk."

Yes, for many formal dinners, you can't smoke until after "the Queen", nor can you get up to go the loo.
A friend attended a formal combined forces dinner and discovered that on occasions "where ladies were not present" (tricky as some of the officers were ladies) a wellington boot was passed under the table for the convenience of the gentlemen - yuk!
