It annoys me to no end to see restaurants (and customers) waste food. The demand for food worldwide has been increasing faster than our ability to produce food has increased. Why are people so wasteful?
On several occasions, I've been in Chipotle, when the person ahead of me changed their mind about their order. The Chipotle employee was left with a mostly made burrito (or whatever) that he couldn't really do anything with so they just throw it in the trash. This rubs me the wrong way because I'm someone who has voluntarily given up eating meat for the sake of the world whereas the person right next to me not only is consuming meat, but is throwing meat straight into the garbage.
I understand that the restaurant would rather please the customer so the customer comes back again at the cost of wasting some food. However, it seems kind of silly that a customer could theoretically change his mind multiple times and waste many times the actual ingredient cost of what he purchases with no penalty. I'm not exactly sure what could be done except that the customers need to change their attitude toward food.
