I think my biggest pet peeve is people proving the "Ugly American" stereotype. Filthy, Rude, Inconsiderate, Selfish, and downright disgusting.
Case in Point...-I saw one due, probably 45ish, picking his nose and wiping it on the seat in a bus to POP.
-Saw another 'diet-challenged' woman that (I swear on my soul) looked exactly like Roz on a scooter literally RAM into a woman that was walking in MK, had the nerve to scream at her that she was "In my path!"
-Some people need to learn to hold their gasses in while in queue lines... I don't appreciate your flatulence!!!
-I'll repeat the sentiments of others here: USE DEODERANT! I don't care to smell cold cuts emanating from your pores!
-If you cut me in line I will make sure to make a fool of you, I don't care if you "no comprendo"!
-Wear family appropriate clothing. No one wants to see your butt crack (or cheeks), and I don't like when some woman is walking around TL or BB in a Thong... Makes things awkward with a 15 year old DSS who is now drooling...
-People who think they are the only person waiting after Wishes that is exhausted, sore and cranky from being at MK all day and walking 15 miles. WE ALL ARE, and you are not special and deserving of a second seat on the bus because you need to rest your feet.
Just be considerate! I love WDW, and so does the family. We absolutely rush to the showers every night at the hotel just to wash off other people's nastiness, let alone our own sweat and park grime.
