You can never have too many work shirts.
This has come up previously so I pointed out to Mrs Nobby that the number of shirts made no difference to the washing/ironing volume – that was only affected by the number of days actually ‘at work’.
By having a plentiful supply my need to go shopping is greatly reduced leading to a reduction in fuel costs (and the impact on the environment) and I am less likely to end up inside for beating any of the living brain-dead people that tend to frequent shopping centres, to death, with their own shoes.
Strangely, it was the latter argument that won the day :-/
