我在2017年出版的一次通過新多益550分的書中，看到雙人對話有一題文法題覺得怪怪的，
想說請教板上各位。對話如下
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.
目前我知道綠色底是同位語句型，然而我比較有疑問的是有關紅色字的部份，
紅色字是完整的句子，為何沒有連接詞？
