Worst disturbance: me, with an ANC headset, listening to some music or documentary.
Then a burst of laughing coming through all this sound engineering – the VP marketing, discussing by phone with some 1K-followers "influencer".
Yeah, the same VP that says that she needs silence to focus on the email she's writing when the intern ask her some important question.

Just made a 10-minutes change on the website for a client for free while the company originally in charge of her website development wanted to charge her 660€. For a simple <script> tag.

Tomorrow, my team will receive TV reporters for an economy magazine.
We'll have to fake a meeting and the Marketing Officer insisted that everyone has to be present.
I wanted to do teleworking on that day because of the huge strike of the public transports.
Guess who will wake up at 5:45 tomorrow morning?

So, as the lead UX/UI designer, I was working with the marketing officer on the new e-mail template of the company. It took us at least one week to get a good settle – 'cause, you know, she's so skilled on that – doing back and forth and arguing on every detail.

Then she sent me a PPT file with the content and wording for each kind of e-mail.
After 3 days of work, I finished implementing the template and pushed the project in production.

~3 months later
MO: How's your work going on the template?
Me: Erm, sorry? You mean, the e-mails?
MO: Yes! Can you show me the result?
Me: Well, the result is online for...like...3 months?
*Surprised* MO: Hum, yeah? But I didn't validate it!
*Wince* Me: Well, yes, you did, we worked together on it and we finally found a nice settle.
MO: Yes, but the content? Can you send me one of each kind so I can double-check?
Me: ...
*to the rescue* CEO (and husband of MO): It's OK, I've already validate them.
MO: Oh, ok. But I want to double-check. I'll do it later, ok.

~3 weeks later
MO: Can you tell me how I can receive the registration e-mail?
Me: ...
*to the rescue, joking* CTO: Well, did you try to turn your computer off and on again?
MO: Oh, you really think this will work? Let me save my work first!
Me: *BOOOOM*

TL;DR: The marketing officer of my company does nothing productive and is making the company losing a lot of money, but she also make me lose my time for bullshits.
At least I can laugh about it on devRant.
