I use cash whenever I can, call me an old farty luddite, I care not a jot
I find cash very useful around birthdays, anniversaries etc, the wife knows I've taken £200 from the account, but has no idea where I've spent it. If I use card payments, she knows where I've spent the money and probably what on.
oh, and I will gladly pay (for example) a plumber £20 cash to replace a tap instead of £40 'through the books'. This may be due to the fact I am unable to claim tax relief on my 3rd London residence, for a fancy structure to house my ducks in the duck pond, and for the 4 members of close family I claim are personal secretaries
