When Scranton tells her story she goes into great pains to describe the setting and in particular the central office in which the story takes place. She begins with an overview of the second floor in general:
"...our offices were around the building and then there was a
centre office building, a large
bullpen kind of office on the second floor, that was
the office of the Texas School Book Depository."
She describes Reid as being the supervisor of this office. She then describes how she and her work colleagues "were milling around" in this office as they were "locked in" by the police. It is in this setting that Scranton describes Reid saying "that Lee came to the door with a coke in his hand". In this context 'the door' can only refer to a door of the second floor central office. In no way can this be construed as meaning the front entrance of the TSBD.
And yet Ms Reid has nothing of Mr Oswald's asking her "What's all the excitement about?" in any of her official statements, which all have her initiating the exchange and his mumbling something intelligible back at her.
From her W.C. testimony:
Mr. BELIN. Could you even remember one word that he mumbled?
Mrs. REID. I did not because he kept moving and I did, too, and I was just not interested in what he was saying, it was just the excitement of time and I didn't even say, "What did you say?" because I wasn't interested.
Why this change in Ms Reid's story?
Scranton misheard. Misunderstood. Mis-remembered.
There is no mystery here whatsoever.
All that matters is Scranton confirming Reid was telling people about her encounter with Oswald in the immediate aftermath of the assassination. She may have got some details wrong, so what, she's human. It's the context of the details that matter.
In your desperation you have to grab on to any small detail in the hope of making the context go away - Reid telling her work colleagues about an encounter with Oswald, coke in hand, in which she commented on the president's death, immediately after the assassination.
What evidence do you have Reid's encounter with Oswald happened at the front entrance of the TSBD? If you absolutely no evidence whatsoever I wouldn't bother answering if I was you
