It drives me nuts. I do donate to a select few charities, but these people make me feel guilty when I walk past without donating (I don't give in, mind you, and my conscience clears quickly!). And the are collectors, not volunteers - they earn good money
But it's not charities that have griped me today, it's shops. Every checkout you get to the assistant asks 'do you have a loyalty card?' 'No, I'm not interested' I reply. 'Would you like to apply for one to get great savings etc etc?' I've just said I'm not interested! Everywhere you turn, someone is trying to get a few pennies out of you
