I am just lilke the majority here. I clean my bag out every single time I change out my bag, which is at least 3 or 4 times a week. I can't stand papers and receipts or whatnot just flopping around at the bottom of my bag. I have a close friend who is the total and complete opposite and I find it totally amazing that she can dig right down into the bottom of her bag and pull out exactly what she was looking for amidst at least a pound of old receipts, broken pens, paper clips, gum wrappers.....whatever. She never cleans her bags out at all. That would drive me up the wall.
