Disappointing

thinking you’re biting into a (chocolate covered) carmel and finding it’s actually an unidentifiable and mysterious nougat filling
cracking open a peanut and finding it empty

getting really excited to watch your latest NetFlix film, only to find they sent the wrong movie

Netflix sending the right DVD but its damaged and therefore unwatchable

 the potato to air ratio inside bags of chips

your favorite menu item is all sold out

getting 10 pieces of snail-mail and all 10 are bills or junk

Tiger Woods

flat soda

thinking you’ll have a snow day and only getting a 2-hour delay

cloudy days at the beach

spending an hour to curl your hair and then walking outside into a wall of humidity only to have it all come undone

going to a Broadway show and an understudy is in for the Tony-winning lead actor

90% of March Madness brackets

American "news" programs

wearing new white pants and spilling red wine on them

burnt cookies

pistachios that have no slit

american airlines (all of them)

ordering a steak medium and having it come well done

Windows Vista

sequels

How about you, what would you add to a "disappointing" list?
