Serving tongs can be used in various places, just think of a buffet. To keep a buffet as hygienic as possible, it is important that there is a separate serving tong with each separate tray so that you can scoop with this tong. It would also be very unsanitary if people started doing this with their hands. In addition to a buffet, these tongs can also be used in the kitchen, for example when grilling meat. If you turn the meat with a pair of tongs, the juices will stay in the meat and the meat will taste better. This is better than when one punctures it with a fork, because then the juices are lost and that is a probe.
