Design Blunder ?
Sometimes we do design mistakes while trying to target better our customers' needs, without asking them.
Here's a joke about new rules for 2008 and a new pill bottle, created by the famous US retailer TARGET, to convince its older customers.
"New Rule: Stop screwing with old people.
TARGET is introducing a redesigned pill bottle that's square, with a bigger label. And the top is now the bottom. And by the time grandpa figures out how to open it, his ass will be in the morgue. Congratulations, Target, you just solved the Social Security crisis !".
Not very elegant , but maybe very true ..
