There can be 50 buggies lined up in front but I will always pick the one with the squeaky wheel.
Everytime you get behind the person with only 2 items thinking you'll escape from "shopping hell" faster...they will whip out a ziploc bag of change and proceed to count out the total in pennies & nickels.
You will forget at least one important thing that you needed and only remember it when you are pulling up to the house with the rest of the stuff.
Those thin little plastic bags will break when you least expect it (normally on the front porch), and be surprisingly tough to tear open when you tie a knot in the top that you can't get out.
