Infinitely annoyed by my client's inability to take action.
They're even starting to annoy ME and it's not my business, nor my client and not even my line of work.
Well, they finally did take action. Sort of. "Can you please use your personal laptop for the time being?"
I'm a contractor and it's my limited company's laptop -it's what it's for, for chrissakes - so I'm fine with it. In fact, I suggested it to them when they first contacted me. But no; they'd provide me with a computer, I must not use my own.
Two weeks later, four days billed per week but with little actual work carried out, we now do things my way.
