Hi, Anton Shepelev : All!
I read your message from 16.03.2020 22:30

How  do  you  find  the grammar in the following de-
scription of an incident from my workplace?


-----Beginning of the citation-----
A colleaque leans into the doorway of my office  and
asks me rather amiably:

-- Anton, will you go to lunch with us?
-- Yeah, directly, -- answer I,

 upon which he leans out, makes a step down the passage, and
 exlaims "Oh, fuck" in gunuine anguish.

 I grew surprised and embarrased because other people had seen and
 heard this unexpected reaction to my harmless answer, and went to
 investigate. My colleague had sworn when he badly struck his
 shoulder or elbow upon the door jamb or some such structural
 element while clearing the doorway
----- The end of the citation -----

Directly???
Taking aside "directly" I think that the question "will you" demands the answer
like "Yeah, I will".
IMHO it is very unusual how you switched times from present to past. I believe
you should use the past tense in every sentence. "A colleague leaned... and
asked me..."

Do you think that "Yeah, directly" means the same as "Yeah, surely"?

PS: also note that your direct speech punctuation is like in the Russian
language, not in English.
+
colleague
genuine
embarrassed
exclaim

Bye, Anton!
