It's only a little example but it made me happy on a wet Monday morning.
I happened to ring my ds this morning when he was at Tescos so, never being one to pass up an opportunity for biscuits, I asked him to buy me some rich tea :).
When he got home he told me he'd had to leave his coffee at the checkout because he couldn't afford it <and> my biscuits. A man ran out after him shouting "you forgot your coffee". Ds said "I haven't paid for it" and the man said "but I have"!
