That may not be your point in this comment, but in your original comment you listed several things (taking home leftovers, keeping sauce packets, hanging onto free pens) that you labeled as low-class indicators. These are only indicators of being low-class if they are not done by a significant number of non-low-class people.

My point was that there are actually some people who are quite wealthy/comfortable who do these things also, and that some people (like law-school-me) react positively to it. The point is that people who do this because of their current situation or past situation need not feel embarrassed or odd for doing this, because some people see it as practical and commonsense.
