How about shopper habits....grrrr
Self or Express Checkout: We realize this may be a novel concept to some, but please try to remember that the Express checkout is supposed to be fast. There is a reason that they put limit 10 or 20 items on the sign right in front of the register line and that the register itself has about 5 square feet of counter space. It is because those lines are intended for us shoppers who are picking up a package of lightbulbs, not those of you who are doing your heavy duty grocery shopping for the whole family. This especially goes out to those of you who are shopping with your 4 children and 3 of their friends who try to use the Self-Checkout for your 2 carts full of crap while talking on your cell phone. Please let one of the highly skilled cashiers help you so that it only takes us 5 minutes to check out instead of 25 minutes.
Shopping Cart Orphans: Just about all shopping centers and stores provide cart corrals for a reason... please use them. It is not that hard to walk the 15 feet from the back of your car over to the cart corral to put the cart out of the way. And the frustrating part is that the people who do this are, of course, leaving the cart behind so it isn't their car that gets dinged it's ours.
Price Check: Granted, this one can happen to just about anyone. We don't expect that an item we've chosen to purchase will come up without a price -- or often we may not notice that the tag is missing. Nevertheless is there anything more frustrating than waiting in line behind the individual who brought 50 items to the Express line only to find out that item #49 is missing a tag so we now have to wait for the price check also? And this is one of those things that always seems to happen when you're in a hurry.
Parking Space Stalker: These are the people that will sit and wait for 5 minutes to watch someone walk to their car, put their bags away, put the child in the child seat, etc. All to save themselves from having to move 4 spots farther down in the row. If you have a medical reason for doing this (trouble walking, handicap, etc) then you get a pass as long as you're one of the drivers who are intelligent enough to avoid sitting in the middle of the aisle so that other drivers can't get around you. Otherwise, we like to laugh at these people as we drive around them, park, do our shopping, and then wave as we pass them still waiting for their spot on our way back to our car.
The Crude Negotiator: Another of our personal favorites, this shopper is the one that will hold up an entire checkout line because they were about to be charged $0.30 too much for their bananas on a grocery bill that is about to total $150.00. Congratulations on holding your ground for the principle of the matter. Meanwhile the rest of us in line are counting the number of items you're buying that could be used to permanently disable you.
...I'll admit I haven't read through all these pages so if some or all of these have been mentioned....sorry!
