As applies to some wastard that would spend $335 on a cup of espresso, I cannot answer that first question, but I sure as hell can answer that second one.
No, it’s is not. This isn’t even close to a case of sour grapes, I can 100% objectively state that there is no cup of espresso on the planet (or anywhere in orbit) worth that much. The second you’ve expressed willingness to pay that much for a fucking cup of coffee, your assets should be ceased and their value used to cover costs of people in need.
(Yes, I understand this could be applied to many things: I spend some of my own funds on purely selfish pleasures, but I like to think I do it as a reasonable level. Perhaps we need a formula of “average cost of goods” compared to “idiotically overinflated ego drink” or something like that.)
