so you gave the costumer the change dur + the $00 bill? not a good thing.
first off it will go on your employee record. at my company you are permitted up to a certain amount of $$ mistakes before @ 6 months before they will let you go.

go slow. go very slow,=..use the function on the machine that tells you exactly how much charge is to be dispersed. always.

they treated you different because they didn't lose $100+change for the company that day, and now they have t 0doo a close audit of all your shifts to see what else occurred

it is a big deal. a few dollars happens, but those in excess of $100,,then there is an issue

I worry for you...between this, your outbursts and behavior it seems like you must be running out of time there

what did the life coach day?,
