McDonald's

Hi...I went thru the drive thru & ordered a cheeseburger with extra pickle & extra onion & a small fry. I go to get my order & was handed a breakfast burrito & oatmeal. So I drove thru the drive thru the 2nd time hoping they'd correct the order & was handed a chicken sandwich. I then parked my car, got out & knocked on the window holding up both bags of incorrect orders & a guy came & I explained what was going on & showed him the receipt. Finally I got my correct order, but was still frustrated with the whole ordeal. This can't keep happening. The whole time I spent in drive thru was at least 1/2 hr.
