When you say "almost 2" instead of 1.7 because you're not sure your customers understand the decimal system.

@qwert computer repair shop. My customers are general public in a.. well... fairly rural area.

I generally assume everyone is a complete idiot until they prove otherwise. They rarely do :<

@Root I do the same thing, except with the intention of trying to be helpful. This has on occasion made me decide condescending.

@antic s/decide/sound

Haha... ha.
That hurts.
I failed a threshold question at an exam (multiple choice), because the result that I got was 1.3, and the choices were 0.1, 1, 10, and "Other".
Choosing "Other" and writing 1.3, and explaining how I got it below did not count. I contested the result, in vain. The verdict was that I should have rounded.
That resulted in a lower grade, and a lost scholarship.

What... The... Fuck.

Sounds like a school you should run away from as fast as you can...

@RiderExMachina that was my graduation exam. I was already out. But the results stifled my future prospects.
