I don't know what the deal is, but I know this:  I like other people's stuff more than my own.  For example, I could get lunch from Subway every day of the week.  I like their simple sandwiches and their relatively low prices.  But when I buy the same ingredients from a food store and make the sandwich myself, it's not as good.  I'm not sure where the disconnect is, but for some reason my sandwiches are always inferior.  Maybe it's because I'm using different brands of ingredients.  If anything, I'm using better brands so this should actually improve the taste of my sandwiches.  Maybe it's the fact that I make my sandwiches in the morning and eat them 4-5 hours later, whereas Subway makes my sandwiches 5 minutes before I eat them.  That could definitely be where the problem comes in.  But I've tried bringing all my sandwich ingredients to work and making the sandwich there, only to find that my sandwiches still lacked something. 

It's the same with Dunkin Donuts coffee.  I'd rather pay over $1 for 8 oz of Dunkin Donuts coffee than make it myself.  Even when I buy the prepackaged DD coffee and make it at home, it tastes like motor oil.  I suffer from a complete inability to make coffee.  I don't know what my problem is, but I know that my coffee sucks.  So I'm more than willing to pay for a cup of fresh-brewed DD.
