Label-reading isn't an issue for me because I've always done it; it's fascinating to me what sorts of things companies will do to make their product look better than it is. (Did you know that fat-free graham crackers actually have ten calories
more per serving than the regular kind? Gotta love when they replace fat with sugar.) It's just stuff that requires me to involve another person like a waiter or a clerk that makes me uncomfortable.
The phrase you used, Ringmaster--"high maintenance"--
that's what I fear being. Not just with food-related stuff, either; this thread has made me realize that I won't ask a clerk to find a dress in another size, won't call back to check on a prescription unless there's an automated system instead of a person, won't return an item most of the time, won't ask a waiter for anything. It all goes back to not wanting to be a bother, not wanting to be high-maintenance--it's totally silly because I am a sweetheart customer and a big tipper. I know too much about what it's like to be on the other side not to be that way.
This thread has made me resolve to be a little more assertive (but I promise to be courteous and tip well still).
