Take on the lack of flexibility

I walk into the local Starbucks today and order a medium vanilla chai latte (not for myself) and when I get the receipt I'm flabbergasted Not just because this concoction comes in at the price of a 12" meatball sub at Subway, not because it's got about the same calories as that 12" sub but because the total comes out to $5.01.
This is where these chain restaurants have it all wrong, by not having the ability to lower the price of an item slightly so that I don't have to dig around for a penny. I'm sure that id they did they could make it up at another spot -like charging an extra $0.02 for soy milk or something- but the fact that I had to break a dollar today to come up with the one penny is ludicrous
