You're eating at a restaurant when you smell it. The sent of over-used perfume interferes with the taste of your Club sandwich. If someone can smell you before they see you, your perfume is too heavy. Lighten it up.
Going to the movies is expensive. I just spent $254 for two tickets, a large greasy bag of popcorn, and 2 cokes. Its a 10:00pm showing. Why did you bring your 1 year-old child? Face it, when you have kids, you give up your life for a bit. Get a babysitter and leave them at home or don't go. Don't ruin it for the rest of us.
It often happens at the bank, movie theater, or grocery store. It could really happen anywhere. People standing too close to me in line is an ultimate peeve. Please, I don't want to smell your coffee-bagle-garlic-cream-cheese breath. Back off.
