Etiquette tip while chatting with someone over food:
Let’s say that you’re meeting with a friend for brunch. You order Eggs Benedict, she orders banana pancakes. During your chat, you bring the cup of water to your lips. Just as you’re about to take a sip she asks you a question. You answer your question with your mouth right over the glass.
Please don’t do that. Take the time to take a drink of water, put your glass down, then answer the question. Time isn’t so pressing that you need to answer it right as you’re taking a drink. This behavior indicates that you are so pressed for time that you can’t slow down and enjoy the moment. Talking into your glass muffles your response so that she can’t hear you. It makes conversation more difficult.
Also, use a straw when you can. Those glasses aren’t always cleaned well.
