Tactical Seatage

the art of tactically positioning yourself around a table in a restaurant.

Those who are "tactically sat" are not hampered by other people and have free and easy access to food and restrooms.

Tactical Seatage - When going for a buffet with friends, never be the first one in when it comes to "scooching down" a bench that is blocked in by a table. Rookie mistake.
