Gross? Stingy? Frugal?

Which one is this?

I used to use a fresh piece of dental floss every day. Until it hit me. 

I don’t get a fresh toothbrush out every day. Why was I getting new floss every morning?

So now I use one bit of floss for several days. Unless my gums bleed. In which case I toss immediately. Normally I use two pieces a week and just wipe with my fingers. And then I lay the floss over the floss container. 

So my stack is going to last me years. 

  
Frugal? Gross? Unnecessarily stingy?
