It’s very common to see snacks, such as pretzels or chips, casually set out in large serving bowls at a social gathering, meeting, or in the employee lounge.
When serving snacks in this manner, please include a serving utensil so hands are not dipping into the bowl and touching the food other people will be eating. On the same note, please be sure to use the serving utensil provided.
If you’re in a jam and do not have appropriate serving utensils, use a cup or small bowl. Perhaps this is not the most elegant solution, but in a casual setting, it is much healthier than using your hands and making it a community bowl.
