<human>: Provide a brief overview of the text.

here is mine...
I used to work at a retail store and a lady came in to make here store credit card payment. she hands me a check and some cash and seems kinda rushed as she tells me to make it as one payment. as i say that my register crashs, so i inform here that i will need to use the one 4 feet to the right. so she slams her card check and cash onto the counter and says HERE IM NOT MOVING!
i then reply that that's not possible they have to be processes separately. she replies WHATEVER! and throws her arms in the air. i process both payments as quickly as possible so i dont have to see her anymore. and i ask her to sign the keypad thing, which she did very roughly. 

now on the key pad it says very clearly that you are signing for X.XX payment amount is this correct? and she signed it twice for 2 different payment amounts.

i then staple her receipt and check to the mountain of coupons that printed out, she tears off the coupons and throws them on the floor on her side of the counter. 

10 seconds after she paces away a co-worker with her eyes wide open tries to warn me but only ends up saying "um" and right as i turn around the lady shouts at the top of her lungs "I GAVE YOU ONE THING TO DO, ONE THING AND YOU DID IT TWICE!" i replied "did you have a question about your payments?" and she stormed off.

weeks later a lady i don't recognize walks up to me and starts apologizing for her behavior. i had to ask her when the thing happened that she was apologizing for to connect the dots.
<bot>: She got mad because i reminded her of her recent EX-Husband (and I'm like 1/3 her age so this also confused me)
