Oh my, oh my, oh my.

Poundland.  A treasure trove of bargains amongst the tat.  I love finding a bargain, but today I had an altercation at a till. Bip, bip, bip went the items.  £2 went the till.  I had more than two items.  As I (thought) I was handing over a £10 note, I queried the bill;  bip, bip, bip the items went again, I handed over another note and then wondered what had happened to the first one.  How could it possibly disappear??? I rummaged through my bag, my pockets...the floor - no note.  The lady on the till called a supervisor and off they disappeared to do a till check, leaving me to ponder the missing note.  For ages.  And then I realised - I hadn't had a £10 note, having spent it earlier.  Mortified...
