When we have company Nomikai, a business drinking party, there is a rule on which seat to take.
The basic rule is,
・A person in a highest position of the group, ① takes the seat further away from the entrance.
・A person in a lowest position of the group, ⑧takes the seats closest to the entrance.
The reason is,
When in the position closest to the entrance, it is easy to make order and serve out all the drinks and foods for the group.
This means he/she will be the busiest person in the group.
In Japan, commonly speaking, the person in a lowest position works harder on this kinds of trival duties or tasks for higher person, so she/he should take the busiest position!
Enjoy your Nomikai in a proper way :))
