And the worst part is that they tend to increase the price when they do that.
They also redesigned the medium bottles of Gatorade and I believe they took out a couple ounces. But since the bottle is shaped differently it's not obvious unless you actually compare the number of ounces on the new and old bottles.
I was reminded of one of biggest pet peeves the other day, when people get a pet, but have no idea how to take care of it or are unable to take of it for some reason. Getting a pet is not the kind of thing you can just randomly do on a whim, you need to do your research and prepare. You need to make sure you have the supplies and a vet, and it's a larger animal the trailer or whatever you need to transport it. You don't just bring home a dog, or a pig, or a horse, and then start to research how to take care of it, and getting supplies. This is an animal's life you are taking responsibility for, not just a cute toy you can occasionally take out of the box to play with.
One of the main reasons Great Danes get turned into to shelters is because they got to big. The one thing they're best known is their size, so how clueless do you to be to get one and not know it's going to get big?
