I'm sorry but I despise being overcharged for anything. If I go to a restaraunt and order something with cheese and they don't put it on but still charge me for it, I'll go straight to the mgr. and get the ticket fixed. I refuse to pay for something I didn't get. I think the OP should first call the restaraunt and politely tell the mgr that when they totaled the bills that night someone accidentally overcharged you .12 and that you would like a chargeback for those $0.12. If the mgr is being an @$$ about it then call up your CC company and dispute the charge saying you have a receipt which proves what you authorized and they charged you more. The CC company will either A. refund you the $0.12 or B. Refurnd your entire $35.12. They will do neither if you haven't made any attempt at contacting the mgr though.
