I was especially intrigued by Stephanie Rosenbloom's article in the New York Times today entitled, In Certain Circles, Two is a Crowd after I was at a restaurant with my family two nights ago and was particularly disturbed by a very drunk and obnoxious older man as he bickered loudly with his wife. The volume and tone of their interaction definitely intruded on my personal space.
Yet, it's not only a person's behavior that can effect personal space, it can also be the brands that someone uses. Think about someone bumping into you while they are listening to their iPod or loudly talking on their cell phones. Likewise, how does it make you feel you pull up to a stoplight in a small car and a Hummer pulls up next to you?
Brands do effect personal space and in turn, that interaction effects brand perception.
