What's so annoying about this, at least for me, is that it's not the important decisions this happens with - important decisions have pros and cons I can consider and discuss and make a rational choice (usually tempered with a bit of gut feeling).
But if I have two different things to eat in the fridge for tonight, it'll take me forever to choose one even though it really does not matter which I pick. Same with watching DVDs - I can hem and haw for ages about which one I want to watch tonight. And while I'm doing all this hemming and hawing, I'm not actually doing anything else, so it's an incredible waste of time.
Restaurant menus, to get back to the OP, aren't quite so bad for me, because there usually won't be all that much on them that I even like. As a vegetarian, if I'm really lucky, there will only be one vegetarian option, which is kind of depressing but makes things marvellously simple. A while back, though, a friend and I went to this excellent vegetarian restaurant, and the menu was full of interesting-sounding things. That was tough
. In that situation, I just make myself say something when the waiter asks, and remind myself that it really doesn't matter all that much.
