Can I sue If I was overcharged by a restaurant cashier which resulted in my bank account being in over draft and the manager was aware or the issue?

You can sue for anything- whether you have a suit worth taking to court is another matter. In general, a civil suit seeks damages to restore you to the condition you were in prior to the event. Only rarely are punitive damages awarded- for the purpose of punishing someone for intentional, repeated wrongdoing. In your case, the damage would be the amount you were overcharged (if it has not already been corrected) and the amount of the overdraft fee that you have paid. In many areas, you CAN file a claim in small claims court for a small fee, and do not need an attorney. You may also contest the overcharge of your account with the bank.
