"Problem" Research

In my research, I have discovered a few things in the world that I consider problems.  I think that at this point in time, there should be better replacements.  First of all, most people have called a big company on the phone and have been put on hold for more than 5 minutes.  This is bad for the customer because he or she gets annoyed and may hang up.  This is bad for the company because they may lose business.  Also, lockers should be laid out differently.  Currently, many schools have about 50 lockers in one block, making it difficult for every student to access their things.  This is annoying and inconvenient.  Finally, overhead compartments in airplanes should be redesigned.  There is never enough space for everyone's carry on bag.  Also, the maximum dimensions for luggage are very specific and often hard to meet.  It is difficult to access your things, especially when you are asked to sit down.  These three things are problems in the world and should be improved.
