Going into a Gap store and finding Hip Hop/(c)RAP music playing loudly over the speakers.
Any singer that decides to put words to Sleigh Ride. HEY FARMER GREY, I'VE GOT A DECEMBER BIRTHDAY TOO. Don't mean I want people to sing about it.
The above with that irritating "ring-a-ling-a-ling-la-ling" background.
People who sit, spreadeagled, in the bookstore aisles while reading books they have no intention of buying
Restaurants who treat you like you've been blacklisted (seriously, I was there one night with a group of people and the waitress served everyone BUT me, and even leaned against me to serve others in the group!!!), then ask you back, treat you nice for a week or two then it's back to the same treatment as before. I noticed said restaurant doesn't have many customers since they axed the karaoke show I was attending there. Perhaps I wasn't the only one treated so horribly.
Wait staff who wait until you've taken a bite of food to ask how things are with the meal, or if I need anything else.
People who walk down the street at night with dark clothes on, or just a strip of bright clothing.
