'There’s a wagon waiting on the quayside when we land. We take the mussels off the boat and they’re put in the wagon, the wagon drives away. And then it's a 26 to 18-hour transit time from north Wales to northern France or the south of Holland. If they order from me on a Monday, then they expect the wagon to arrive on a Tuesday because they want to...sell them on a Wednesday. It’s that seamless. Anything that introduces delay or uncertainty or whatever you call it in that process becomes an issue in terms of the supply chain. That’s not just a small problem. Nobody wants to eat mussels that are gone off.'
