Ballet Chips

I went into a shopping mall, where I intended to visit a betting shop. I knew how to place a bet and how to win. (Not actually true.)
On arriving at the place where the betting shop should have been I discovered it was now a fish and chip shop. Serving was my friend S. She in fact only served herself fish and chips then came out from behind the counter to speak to me.
We sat outside on a bench. I offered to massage S's feet and noted she was wearing silver ballet shoes.
These shoes had so many laces and straps that we decided it wasn't worth the effort. S then handed me a chip.
Result.
