Still on the topic of Sprawl Mart and impossible requests, this happened last night:
Our local Sprawl Mart has the usual row of checkout registers, 1 customer service (returns, exchanges) area and then a seperate counter that sells money orders, stamps, wires money, etc. This area is kind of roped off and there is a large placard that lists exactly what services they provide. I think it's pretty well labeled and clearly not a checkout for usual purchases.
2 older women were working up a lather standing at this counter and trying to check out their overflowing carts.
OL1:

WHAT do you mean I can't check out here, hon.
Employee:

I'm so sorry. This area is for (lists services). I can't check you out. You'll need to go to a register.
OL2:

We NEED to check out, hon Why won't you help us, hon?!
Employee repeats above, gesters to row of registers/cashiers.

OL1:

See, that's the problem with this store, hon. Every time we come here we can't get waited on, hon. This is outrageous, hon.
On and on they complained. Loudly. And every sentence ended with the word, "hon".
Finally a manager arrived and very firmly pointed them in the direction of the cashiers and basically told them to move to a line or leave the store altogether. He was not rude but very very firm. This did cause the 2 ladies to move to a line, where they continued to grip, complain and "HON" until they were waited on by a cashier. It was insufferable and ridiculous to watch.
