Oh yeah, in the spirit of the OP, one other thing you can do if you're still attending is make sure you always have at least one or two territories checked out that you never actually work.
Better yet, see if you can get them in areas that have a reputation for being "productive". (JW code for the poorer part of town.) In this way, you can personally prevent JWs from cold calling on two territories worth of your neighbors who are most likely to fall for the virus. You can even make one of these territories your "personal" territory that you hang onto indefinitely as long as you report it as "worked" every few months.
Every little bit hurts.
