If Tang Mei continues to ask 'why', Wei Yi Yi would tell her that, whether they are the boss or a simple employee, as long as they have a girlfriend, they would want to have a 'plus one' and show off that girlfriend at the company outing!
So no matter what, Ye Ai Ning is a must!
And what would she do with just her Boss? If it really just them, whatever he wants or whatever he needed, she could only nod her head. For she would be stuck to accompany him herself and leaving hin whenever she wanted would be hard.
The important point is, that would be boring!
As for the other consort, she simply brought them because there's a limit on being a thirdwheel. She wanted to be a wingman, not a sore eye.
Also, they deserved this additional incentive. They worked hard for that! Since we don't have insurance, might as well pimp out all the bonuses!
