Was working through a cashflow forecast with a business mentor.
I was talking about VAT and he went on to take my figures and then explained to me how to take out the VAT element of my figures to give the net rate. He then did the calculation in front of me - telling me how he'd done it.
Meanwhile - I was trying to tell him that the figures were net and I just needed to add the VAT on in the right column. I'm also capable of working out the VAT element easily.
I mentioned about company cars. I politely listened as he explained what HMRC had done, explained about benefit in kind etc - I knew all that already but he never bothered to find out what I knew.
It's quite frustrating when someone doesn't listen to you and then explains something for 5 minutes that you already know.
