Earlier quoted context omitted.
Are you asking me if the 50% figure is accurate? Because it is.
No. I'll try again. If you order a salad and eat the greens, but not the dressing served on the side, you just wasted 90% of the calories. See the point?
Is your problem that I used calories as a way to measure the value of the food?
Should I have used price? That's not valid in my opinion. Wasting a spoonful of expensive caviar is not as bad as wasting 10 kg of rice. And I have no problem people wasting their money.
I just don't get your point. Is there a way to look at this situation (deliberately ordering something you know your gonna throw away to not inconvenient the staff) and not consider it wasteful?
PS: If your salad's calories is 90% from oil, you're using too much oil.
