Since they are fasting, we need to keep this in mind and be considerate. Don’t drink water, eat snacks or even chew gum in front of others.
When I was working in Saudi Arabia, we had a designated room at my workplace, on every floor, where expats who were not fasting could go and have tea or coffee, snacks, and eat their lunch. People are very flexible, and they understand that not everyone fasts.
And they even allow us to keep consuming food and beverages during the day, just in a separate area behind a closed door. Also during Ramadan, it’s best not to keep consumables out in open view. That includes packaged snacks and even water bottles.
