I just think it is funny how you mix "taking responsibility for ourselves" with relying on a government agency to supply you with the items needed to take responsibilty for yourself. Could they fit it in their budget? Maybe, probably. Do they care? That's the real question.
Yes, the bins are gross and dirty. Yes, the CP's are disgusting. Yes, lots of people walk barefooted on the gross, disgusting floors. Should we supply booties (some airports do)? Well, we do make you take off your shoes. Should we supply baggies because you are required to travel with your liquids that way (some airports do supply baggies)? Should we start supplying people with suitcases or boxes since you need to have your clothes-n-stuff in something when you travel?
Taking responsibility for yourself also means being prepared. If you dont want your stuff in a gross bin, don't use one. Put your stuff in your carryon. Leave your laptop in the "TSA friendly bag". Use a newspaper (as someone suggested).Bring your own booties. Don't rely on the TSA to provide you with the items you need to comfortably pass security while maintaining a higher than average need for hygienic standards.
I am not knocking you on this, I agree it is gross. But you gotta take care of yourself.
