Heard an interesting debate between 2 people today while waiting for my coffee.
Person1's view is that café shouldn't be charging extra for non-dairy milk (eg soy, almond etc) because it's a replacement for the cow's milk. Person2 said it's because non-dairy milk cost more so café are making up for the "extras". Person1 said that might be the case 10 years ago but now prices of non-diary milk has come down a lot of there is no reason to still charge customers, in fact the charge has gone up as well, ranging from $0.70 to $1 for some places(from $0.50).
Keen to hear thoughts of coffee drinkers what they think? Should cafés continue to charge customers for non-dairy milk in 2021?
Woolworths brand soy is $1.15/L, and cows milk is $1.20/L. So by that metric, no, they shouldn't charge more.
But is there more wastage for soy than for cows milk?
