I don't know how old this food science is but I reckon the white vinegar (which is distilled vinegar, btw.) was used for pickling onions. Many chips shop use up their old stock as best as they can so once the onions have finished instead of throwing the vinegar away they used it to go on your chips. I must admit it is very tasty on fish too.
