Re: I just got back from a rather large data center.
Like, oh, I dunno, CODE, maybe?
If they could code they wouldn't be complaining. They would be too busy doing something actually useful!
Here is the problem; The people who complain will never ever be satisfied. If you give in to them once, they will just come back for another byte of the "I'm offended pie". It's all they know and it's all they can do; They have no other use, skill or ability.
The one and only solution is to starve them of their oxygen by simply ignoring them. Don't answer or respond in any way (just send all comms they spurt to the wast-bin)
