WOW!
Do people REALLY go around telling people "you are spending too much" on things. Lucky for me my friends aren't that judgemental.
Seriously!! Some people apparently have really nosey friends.
I wouldn't even stop to add up how much we spend on alcohol. No one has a drinking problem and we are debt free so there's no issue. We spend little on beer but love wine and DH loves to bartend at home. A great drink is even part of my Thanksgiving planning- we will have delicious grapefruit margaritas for brunch.
To the OP, there may be an issue if the beer drinker's wife has a problem with his spending but in my view unless they are in financial trouble and she's completely frugal then she should leave him alone. Nitpicking isn't good for relationships.
