Ok so as my son is now off for easter I had a cinema voucher for £20 that I have to my childminder to see if she might be able to use this. She said she wont be able to as she has too many children this week. Went to take the voucher back off her kitchen cupbard and it fell down a gap at the back. She doesnt seem overly concerned and said"ahh you wont get that back now" but Im really pissed off as £20 is a lot of money for me to lose. What would you do ?
