Texas Roadhouse

Myself and my family came to your establishment for dinner, my bill was $73.91 + added gratuity of $12.15. I didnt authourize the tip to be taken off my card and the tip was covered in cash! I want to know why it it suddenly on my card now! This is an anlawful act and and I want it removed asap! Not to mention the server not only spilled a drink onto the laps of my niece and mother in-law, but waited till the end of our meal to clear our table! If this isnt corrected removed on my card, actions will be taken. I know its only $12.15, but the service certainly was not worth $24.30 and was unauthourised as I filled the slip out for the $73.91, and left the tip in cash!
