Anyone who works in a shop and has responsability for looking after the cash knows the feeling.
And you forgot to get change on Friday afternoon.
You have a few quid in the till but as the morning wears on (and someone paid with a fifty this am - never helps) the change situation worsens...
...luckily we have a market right outside the door with small change weighing down most of the traders.
At around the same time I'm running out of pound coins they are wishing they didn't have quite so many.
A brief chat and the problem is solved.
Thanks again Manny!
