Check-out Line 

The place where you bitch, moan and cry to the unsuspecting checker who's just trying to provide you a service. You shouldn't do this as usually they don't care about what you're about to say to them about your guacamole jar being out-of-date. They just want to know if your day was alright and if your shopping experience was fine. In all cases, they can just call someone to get you a new one. Be polite please, and learn what the check-out line is actually for: to pay for your products and get them bagged in an orderly fashion.

"Aw man, are we going to the check-out line?"
"Yes, so we can get our stuff checked-out in a decent manner."

Murphy's Law of Checkout-Lines 

"If you aren't in a hurry to leave the store, there will be little or no delay in getting a clerk to ring you up. But if you're pressed for time --- or even more so, if you're car-pooling with someone who is on a tight schedule --- THAT'S when there will be hold-ups galore... a long line in front of you, a customer with one or more heaped-full shopping-carts, one or more price-discrepancies that hafta be tediously resolved (i.e., the puzzled clerk is obliged to walk back with you to the shelf to look at the price-labels, a supervisor or the store-manager has to be called over), a balky card-scanner, etc."

Whenever someone who's giving me a ride is kind enough to let me stop at a store to grab a few items, I always try to make very sure that I have everything all "set and prepared" before I head to the register, so that I personally seldom create a problem (i.e., cause any delays myself with issues like not having the proper payment ready or being unsure of a price or quantity) with Murphy's Law of Checkout-Lines. That way, even if my driver has to wait linger than expected for me to hastily scamper back outside with my loaded shopping-bags, he won't be able to direct his impatient frustration at me --- "Sorry for the delay; I did indeed get everything tossed in my cart very quickly, but there was a long line in front of me, and they were short-staffed today, so they only had once register open."
