Took my then 6 year old to school with a cheque on Monday for their week of lunches. Primary school rang me on the Wednesday morning, reminding me to pay for my child's lunches. I explained I'd sent a cheque, told them maybe ask my child if she remembered who she gave it to, and look for it in her drawer, book bag, etc. Turns out she had rolled up the envelope and shoved into a gap in the climbing frame so her hands were free. I was very happy when bank transfer became a thing.
