Final answer:
Option (3), When dining with the Queen, you must not wear casual attire, eat before the Queen, speak without being spoken to, or use your phone at the table.
Step-by-step explanation:
When having dinner with the Queen, there are certain protocols that should be followed to maintain proper etiquette. Firstly, one should not wear casual attire; formal dress is required when dining in royal company. Secondly, it is imperative not to start eating before the Queen does. This shows respect for her and acknowledges her status. Thirdly, one should not speak without being spoken to first. This rule maintains the formality of the occasion. Lastly, using a phone at the table is considered extremely impolite and should be avoided.
The above guidelines are in harmony with historical dining etiquette within noble households, where every action was meticulously observed and judged. For instance, knowing when to place the napkin on your lap upon sitting at the dining table was important. Similarly, patience and decorum were expected in all forms of communication, represented by the practice of how long one would wait on hold during a telephone call with someone using call waiting.
