- When you have the managers at two grocery stores saving the prior day's newspapers for you to use as substrate - and it's not enough.
- When you select a fast food restaurant and meal based on whether or not its plastic containers can be easily repurposed as snake hides (cough Chick Fil-A salads cough).
- When you go to Lowes or Home Depot the guys in the building materials section immediately ask how much melamine you want this time, and how it should be cut.
- When your feeder supplier gives you wholesale pricing because you spend so much with him each week.
- When someone asks how many you own, and you can't give an exact number.
