Clients love to use the word "Broken" (or synonymous word).

Client: The program is broken. Fix it ASAP.

Me: Ok, give me some details so I can help you.

Client: No, fix it. *Becomes an ass*

Me: Alrighty then, let me sit here doing nothing for a couple of hours. Then say that I tested the code against your original request, and it's working as intended.

Client: Sounds good.

(Pretty sure that's how it went)

Never let customers define the priority levels. It will end in:
- Normal (never used)
- High (used for small text changes)
- Higher
- OMG fix now
- Highest
- the World is ending if this doesn't get fixed now
- different existential plane of priority
- Priority ∞ + 1

People going to the doctor: "I'm sick, and here are all my symptoms in detail."
People who have a problem with their cars: "My car don't work, here's everything I've noticed"
People who have a problem with computers: "COMPUTER DO NOT WORK, THANK YOU"
