has it happened to you?

It happened to me at Monmouth Park. I missed a $250 exacta because of it. The teller put the wrong number on top. I know I called it out right because I had it written down. I went back to the window to change it when I noticed only to get boxed out. It was the last time I've ever left the window without checking my tickets. I only have myself to blame for it. I couldn't concentrate after that.
