I work in a school and we were doing a cake decorating activity this afternoon, so at lunchtime I sent a colleague to the local shops to but some icing, decorations, etc.
On the list was sprinkles. (aka 100s and 1000s)
He comes back with... a sprinkler!
Yes, one of those things for watering the garden.
He said he was a bit confused, but could he really be that dim?
In his defence, there is a small garden. but everything else on the list was icing, chocolate chips, etc. And we don't send out the teachers to buy gardening equipment!
What silly mistakes like this have people around you (or even better you yourself!) made?
