My wife calls me after she went on a Walgreens spending spree this morning. They had a senior (55+) 20% off day, plus she had points on her card for another discount. She guessed with all the things she purchased was about a $50 purchase. She gets out to the car and looks at the receipt and even though every thing was scanned, it only showed one item on the receipt for $14.85. She called and asked what should she do? (we do use that cell phone once in a while) My initial reaction is go back in and point out the error. Then I'm thinking, will that get the senior citizen cashier fired? It is probably about a $30 error. Then I'm thinking...well everything was scanned, so it must be their computer problem and not the cashier's fault, although she should have realized there was a problem with 3 bags of items and only $14.85. I'll tell you what we decided after I see some opinions. I'm just curious what others would do.
