I know this is a thread drift but too good not to tell. Many years ago I and my ex wife and daughter were on a drive about a 100 miles from home. We stopped someplace for pie and coffee. Got back in the truck and the waitress came out as I was fireing up and said, Sir, did you mean to leave a $100 tip? I had left her a 100 dollar bill thinking it was a one? I only had a couple bucks left in my wallet and needed gas! We couldnt have made it home if she hadnt caught my mistake!
