20 Items or Less

OK Is it just me or does this aggravate anyone else? So you are at the grocery store and you are ready to checkout, and you have say maybe 10 items. Then you get to the checkout line and what happens..... the person in front of you has approximately no less than 50 items......what tha!!!!! Why do people do this? Is it just to aggravate other people I wonder? There you are in a hurry to get home to make dinner, you came in rushed to get what you needed and are trying to get out quickly, and then out of nowhere is this idoit with the inability to read a sign that says 20 items or less is in front of you and of course they they take their dear sweet time. Maybe it is just me but I consider this very rude and taxing to one's nerves. So if you are at the store and you have more the 20 items, come on people do the right thing and go to the regular checkout!
