Irritates me professionally when we're asked to do big infrastructure projects with practically no lead-time and the PI says "I will pay". This thinking betrays the belief that it is simply a matter of money.
Well it can be a matter of money, but often an order of magnitude more than they are thinking.
Every time. #sysadmin
There is also an attitude here towards labour. It isn't good.
Before leading with the fact you're willing to pay, you'd better be fucking sure you can afford our time.
