Leaving Things on the Counter (Part 1)

I've never understood this--->Someone will be shopping around the store and will repeatedly walk up to the counter to leave what they're buying there and continue shopping. I can understand if they were buying something large like a toaster or coffee machine.....no problem, leave it there! Hell, I'll probably take it out of your hands and put it there for you.

Why, though, must they "drop off" e-v-e-r-y s-i-n-g-l-e item on the counter while they're shopping? It's not that they juuuuust so happen to be near the counter and decide to leave it there. They could be at the very front of the store......and they still walk over and place the item down on the counter. They could be at the very back of the store.....and they still walk over and place the item down on the counter.

Is that their form of exercise everyday? Doing laps back and forth with "heavy" objects like wooden spoons, bottle stoppers and pop-up sponges?

It not only crowds the counter, it's also a TOTAL pump-fake. Each time they come up to the register, they stay juuuuust long enough to where I think they're done shopping......propose the question, "Are you all set?" and get the giggly, "Noooo, (hehe) still shopping" response.

*Fantasy scenario*......"Oh, (hehe) you're still shopping?" (walk over, grab a basket--clear everything off the counter with one big swipe of the arm) *hand them basket* "Here you go, Dorothy."
