Lay's make crisps.  Or, as they would say, “potato chips” but we're not opening that can of worms again.  They are, like most businesses in the United States, owned by PepsiCo.   They make loads and loads and simply loads of crisps in different flavours and shapes and varieties and, whilst they are available all over the world, they are little-known or appreciated here in good old Blighty.  “Why's that?” we hear you say.  We're glad you asked because we know this one; it's because of Walkers Crisps, which are owned by the same people.  But Lay's are made in different places in different factories by different people using different methods.  So they're quite different.  Try some.
