This article can very easily bring up much deeper ideas based on the findings. For example, how many other things do we tend to dislike (or enjoy less) because of a particular circumstance? This is especially true of first impressions. If you think back to your first impressions of various people, you may find a pattern arise based on your surroundings. Personally, I found a large bias against people I met in less than favorable conditions. After meeting with these people a few times after, I found I enjoyed their company. Similarly, there were people I favored during positive conditions that seemed less than favorable during normal conditions.
These findings may also alter restaurants as we know them (if restaurant owners actually pay attention/care). If a restaurant wants to increase the flavor of their food (and thus the number of customers that enjoy it), they may opt to use a bit more space for quieting the various booths. I know I would enjoy my weekly excursions for curry much more if I had a quiet booth in which I wasn't bothered. I, for one, would be willing to pay an extra dollar or two per meal to have booth dividers extend to the ceiling. I may even be willing to shell out a few more if I know I would get my own "personal" enclosed area to enjoy my food with a friend or two.
