I don't see you so much as entitled as a bit clueless and maybe worrying about things that really aren't that important (borrowing trouble is how my Grandma put it), but what 15 year old doesn't do this? Heck, I know men of many ages who are both clueless and worry too much about little things. I have a feeling the standard for travel in your country is a bit different than it is for those of us in the States. Calling you entitled is like calling a kid who won't eat his spinach entitled because there are starving kids in Africa. That you are so concerned about your health and committed to eating Paleo that you pay for your own food flies in the face of the entitlement theory that has been accepted as fact by several posters.
Have fun on your trips. Just like the rest of us, you have a lot to learn.
