Disgusted!

The restaurant had just opened that same day and we were looking forward to trying something new. My fiance went in to place the order and didn't notice that he had been overcharged. I noticed this as I looked at the receipt to see that we had been charged for 2x 1lb burger instead of a 1lb and a 1/2lb as was ordered. When I queried this with the cashier that the order was placed with she told me she can't remember his face....which she served just minutes ago???<br> She then call who I assume to be the manager and he said he will sort it out. I got my money back, but as I was walking out I had forgotten my change and another cashier called me back to get it. I turned just in time to hear and see the manager tell this cashier \No
