Input: Text: this happened last friday.  i pissed off an important client by telling him that i have to ask for permission because the business he's doing is bigger than my allowed (the max transaction i can do is 3 million daily because i am junior and he wants to do 75).  the client was saying how ridicules i am for not accepting a completely legitimate deal and he needs to consider weather he should close his account here with us.  half way through the conversation he slammed down the phone like how someone would drop the mic and walk away.  a minute later he called back and did nothing but scream cuss words at me for an entire minute, then he dropped the mic again.

i panicked.  this guy is our company's biggest client.  he contributes to 3% of our entire company's business monthly and i am sure to be f**ked if i lose him by some stupid mistake. i cried and reported to the manager, he said he'll help follow up but my heart sank really, really low.

lucy later everything is chill now. later that day, came in person with a huge cheque.  it's so big, the commission i get from it equals to an year and a half of my current salary. he said he feels bad for being so stressed and hopes to continue business with us.

received a letter this morning, i'm getting promoted along with manager.  buffet in a hotel tonight.

morale of the story: never turn down clients of anything legitimate, even if it's outside your boundary of access.  if you fail to do the above, make sure he feels bad for you.

update: the cheque he gave me was rejected by the bank what the fucking fuck

final update: new cheque arrived and deposit is successful, trade settled and my account credited.  i'm preparing for my vacation.

TIFU? Pissed off someone I shouldn't
