What I hate is when they keep messing with the product size....smaller and smaller so that you don't really much notice, then suddenly a few years later, they come out with "mondo" size, which is actually the size it used to be years before. Take toilet paper for example (before this new grande sizing)....Charmin had regular rolls, then little by little the rolls got smaller and then they came out with the "double" roll. Double roll got smaller, so they come out with triple roll, etc. Paper towels are becoming same way.
Another peeve is when they do the "improved" and say they are adding "25% more chicken" in the can of chicken noodle soup.

Start out with 4 chunks (if you want to call it that)...add 25%...wow, they added 1 extra chunk to the entire can!
Here is another one.....tuna. When I was a kid, you opened a can of tuna and it was like a tuna steak. Now, you open a can and it is a can of tuna mush soup. The kicker is that on the shelf next to that crap is a can of "primo" tuna for a much higher cost. It's the same tuna you used to get in that cheaper can.
I love when a product get a new label......"Same great taste, different look" Are they refering to the product or the label?
