These groups know how to maximize donations, and your opinions don't really come into the equation. Get tough... wave them off, mumble "not today," say you already gave, grin like a maniac, whatever it takes to get past them, but don't expect them to change.
What!? "put my phone to my ear," "mumble 'not today,'" "say you already gave"!? Did I miss something? Do these people have guns or something? Look them square in the eye and say, "no." You don't want to donate, or sign, or whatever it is that they're asking you to do. Own it. Act like an adult who has made a decision.
NEXT!
Here's the thing, i ask myself this every time you post here.
Clearly, Damos has a captive and loyal audience here. Hence, Damos gives what the people demand.
Absolutely nothing except for some minor property damage.
