I like to make decision about things in my own time and so really hate being pressured to sign up to things in my door step. Yes, I know the solution is to not answer the door or engage, but I don’t like to just ignore someone knocking.
Just recently someone came, selling one of those food delivery schemes and since it was a product I was interested in, the women managed to talk me into signing up. The annoying thing is that they never want to just leave the information with you. So she pressured me into signing up on the spot. In the past I have also signed up to various charities. I have told myself that from now on I will just respond with a firm “I don’t sign up to things on my door step”.
