Final answer:
One should not snap their napkin open to exhibit etiquette; instead, gently place it on your lap. Appropriate phone etiquette for being on hold is around 5 to 10 minutes, with longer waits depending on context.
Step-by-step explanation:
To demonstrate that you are fancy and have proper manners at a dining table, it is important to adhere to certain rules of etiquette. Contrary to what some may believe, one should not snap their napkin open to show they are fancy or have proper etiquette. Instead, you should gently unfold your napkin and place it on your lap soon after sitting at the dining table. It's a discreet and polite way to begin a meal and indicates that you are ready to start.
Regarding phone manners, if you are on hold, the etiquette would suggest a reasonable wait time would be around 5 to 10 minutes. If the wait extends beyond that, it may be acceptable to hang up and try calling back later or seek alternative ways to contact the individual or company. However, it is important to be patient and consider the context of the call, as some situations may warrant a longer waiting period.
