When you're right...you're right. On another note...I'm 78...and you can bet your booties that I was treated like some crazy old lady that just doesn't get it. That ignorant clerk will get hers someday.
The “excuse” the cashier gave was that in something like 40ish days they were going to change the process, but if you hadn’t got set up for the new method yet the old way would still work. I told the cashier that the it isn’t that date yet, the change was just announced like 10 days prior, and I wasn’t the accountant who handles all that but I had notified them to fix it with HD.
