If I have $30 to spend on books each month, is it better to spend on one book so one author can eat well, or spend it on two books so two authors can simply eat?
Because you're an idiot? Alternatively, because you want to socialise with rich people. In all cases, the better alternative is to buy fish and vegetables for 6$ and cook them yourself for a healthy and nutritious meal.
Spending $12 for a burger is considered "rich"? You pay close to that in most dinners... And the $4 McDonalds/Dennys/JITB/whatever burger is nowhere close to the $8 or $12 burger you get in actual restaurants.
Besides, the point of dining out is not getting stuffed with food on the cheap to avoid hunger.
You know this adds nothing to the discussion, and only encourages people to disregard everything you're saying, right?
I'm a good cook, but my favorite burger place charges around 12eur for a burger and I'm happy to pay it because I can't easily recreate the same at home, and it's freaking delicious.
"Because I want to socialize with rich people" is beyond absurd.
