There's an opportunity there for fish & chip shops to sell another product and make more money.
Most of them also sell a few different hamburgers too. Many of them these days are also Asian-operated, so also sell various Asian takeaway options.
One problem for fish and chip shops selling pies could be the timeframe it takes to bake one, as against the couple of minutes to fry a piece of fish and a few chips.
Can't be worse than those disgusting sausages on sticks they sell.
Some of them used to (and may still do) sell a deep fried banana on a stick if you prefer ... hey, it's fresh fruit, so it must be better for you than a deep fried Mars bar. ;-)
