Mcdonald's

I had an online purchase, waited for order to come out, after 15 min I went in to see if it was close. I was told yes they added they were very busy would be a min. I said yes I could see they were busy, but I could also see that while I was waiting outside every car that was in the drive thru ( which was lined up all way to street both lanes) have all been cleared out and now your clearing out the next bunch that have come up way after I got here and Im still waiting!! Finally I get my order, or so I thought, they handed me one value meal. I told them I still needed my double ¼ lb'er, & 20 pc nugget. 20 min later!!!! I got rest of my order mind you the 1st part was now cold. I look in bag, ok there's the double sauces for nuggets and box under the sandwich. U guessed it got home only to see the box under the sandwich was a regular cheeseburger!!!! Not only was it not my 20 nuggets it was a TINY REG CHEESEBURGER in a BOX not the paper. tells me they did that on purpose. Problem is of course I called complained was told I'd get the coupon in mail blah blah blah, but they don't care, they don't even have to change b/c they know they will always be busy so who cares if I stop going, they will still get plenty of bus. Horrible thing is I was told just that by the manager. She actually told me if I didn't like her store there were plenty more McDonald's to choose from, she would be just fine w/o my bus. Then told me to have a nice day and hung up. What happened to treating people with respect, kindness, and just plain gratitude for my bus?
