I'm covering for a colleague who has 2 weeks of vacation. Everything is made with Drupal 7, and it's a backend + frontend chimera with no head and 50 anuses.

So, last monday i get told i have to show a value based on the formula:
value * (rate1 - rate2) / 2

On thursday, every calculation in that page is suddenly wrong and I get balmed for it. Turns out, now it has to be:
value * (rate1 - rate2) / rate1 / 2

Today, I get told again the calculations are wrong. "It has to be wrong, the amount changes when rate1 changes!". There'll be a meeting later today to discuss such behaviour.

All these communications happened via e-mail, so I'm quite sure it's not my fault... But, SERIOUSLY! Do they think programmers' time is worthless? Now I'll have to waste at least 1 hour in a useless meeting because they cba to THINK before giving out specs?!

Goddammit. Nice monday.
