it's not watered down it just never gets shaken up because it's in those squirty things I think. scientific theory ff
One of the most watered down items that you get regularly, is the vinegar ??? you get in take-aways. Never seen malt. Nearly pure acid which has to be watered down about 10 times or it will burn your innards.
In the east stand near the family area love brown sauce,but i'm thinking it's coffee realy watered down.Try shaking the bottle and it's like shaking a bottle of water. My tip pop into Asda when i have something to eat they have little packs of brown sauce ,i pick a couple up always seem to be too many(i never can judge it right)whats left i take to the match.Handy.
