Not as much, because all drinks must have volume percentage printed, else they will have their brewers license revoked, and must print total volume of drink, else they can't trade. So after some maths the argument will be solved. The argument of "How much is a unit?!" can go on all night (I've seen it do this)Thats a product of, as has been mentioned, the poor labelling by the drinks industry.
If 100% of products had a 'unit' rating on, then there wouldn't be an argument, because it'd be right there.
Likewise, if only 50% of products have a 'cl of alcohol' on, there will still be arguments over how many cl are in a drink.
