I don’t give a toss about peer pressure but a lot of people will. It’s way easier for someone to get an alcohol free beer in a pint glass and hang out with their mates (including not yet announced pregnant women) than standing there sticking out like a sore thumb with a glass of Coke.
As you know, the good lady works for the world's biggest drinks company. Their non alcoholic beverages are first class on taste. I'd agree with you if you said you don't like them because they don't get you p1$$ed but the taste test is no longer an issue. Guinness 0 is amazing, Tanqueray, Captain Morgan Spiced Zero are all bang on the money. I've actually been involved in taste testing these products in design stage.
Clearly a matter of personal taste, but I'm surprised at that. I've been a Guinness drinker for most of my adult life and I consider the 0% to be excellent.
