我在2017年出版的一次通过新多益550分的书中，看到双人对话有一题文法题觉得怪怪的，
想说请教板上各位。对话如下
W:Hello, Good Taste Restaurant. Gina Speaking. How many I help you?
M:Yes, hi there. My name is Josh Tobin. I've got a complaint about your
service. Yesterday my wife and I ate at your restaurant, and one of your
waiters, I think his name was Tony, was pretty rude to us.
W:I'm terribly sorry to hear that, Mr. Tobin. This is not typical of our
service, and I believe this is just an isolated case. We will certainly
enhance the training of our service personnel.
M:Okay, I surely hope so.
目前我知道绿色底是同位语句型，然而我比较有疑问的是有关红色字的部份，
红色字是完整的句子，为何没有连接词？
