Coke vs Pepsi - I want to be asked

I was recently reading a thread on Something Awful about how much customers suck. One person regaled the internet with his tale of how once a person asked for a paper bag and the cashier put it in a plastic bag, since it was all he had, and because 90% of the time the "bag" is the important part and not the "paper." The guy screamed at him for not listening, wouldn't take "We don't have paper bags" as a response, all hell broke loose, and he only left after the manager offered him a trash bag instead.

This story was the precursor to any number of waitresses/bartenders talking about how annoying it is when people make a stink over Coke vs Pepsi. (Though I don't think it's an apt corollary.) Turns out most waitresses don't feel the need to even mention they intend on bringing you the alternate cola, and they CERTAINLY don't understand those picky souls who "demand" a different drink when the alternate shows up on their table. Bartenders virtually never bring it up.

Well, file me under "picky" then, because if I order a Coke I want a Coke, not a Pepsi. When I order a Mountain Dew I want a Mountain Dew, not Mellow Yellow. I really don't see how you could debate the other side of this.

I'm sick and tired of the "they taste the same" argument, because they don't. They aren't even close, and it isn't just us "picky" people that have the superhuman taste buds to tell the difference. Even if it were true that they tasted similar, do you bring everyone who orders prime rib a sirloin because they "pretty much taste the same?" If you didn't serve a prime rib at all would you not say anything to the contrary, then bring the customer any piece of beef you saw as "close enough?" I really don't see how that is much different.

I'm anything but a picky customer, however this is just one of those things that bug me. I'm a little perturbed this makes me a "problem customer." I won't demand a new drink, or make a big stink about it. In the few instances I don't ask Coke or Pepsi before ordering, usually I'll just ask if I can switch when it comes time for a refill. Though, maybe that's part of the problem. All that is necessary for the triumph of evil is that good men do nothing.

I didn't order a Pepsi, or a Jack and Pepsi, I wanted a Coke. All you have to say is "Is Pepsi ok?" so I can change my mind to something that doesn't contain that vile brown-tinted water.

Ok, that was all a tad tongue-in-cheek, but I'm not the only one who's bothered by this, right?

Am I just particularly screwed because Mountain Dew is my first choice, and Coke is my second, while Pepsi and Mellow Yellow rank amongst my least favorite?
