It is irritating and annoying when people do public displays of affection. Seriously, people should be mindful of others and save their romance in private. Yep, that is my pet peeves. When dating, I guess holding hands and light kissing is fine but if you are sucking face like there is no tomorrow go get a room. I am no killjoy, I just have a strong value system. Have a little respect for yourself and for too. Geez.
