Don't you hate it when...

You go to a drive thru and your order is wrong!

Went to McDonalds last night... Trying to stay on point... Chicken sandwich came loaded with Mayo :(

So what do you do when this happens? I took off the whole bun that had mayonanse on it and didn't eat it. Save myself a fair amount of points. How do you handle this situation. I was very frustrated and hate it when I get my order and it is wrong!
