I'm going to lie about finding hair in my food at the resturant
Why would you lie about that?
I want to restaurant to give me my meal for free.
That's not something you should lie about. You could get someone in trouble, maybe even fired.
Who doesn't like free food? C'mon.
If you can't afford to eat there maybe you should find an alternative place for meals. How would you feel if someone lied about a meal that you served and got you in trouble?
