<prompt> Human: Recently had a horrible experience at a bar where I was charged 21.00 for two 4.00 beers. I asked the bartender who was helpful at first and asked the other bartender whether I bought one drink from her. She said yes, but said she charged me for my buddys drinks too.Fine, me and my roommate will figure it out once I see his receipt. Bartender proceeded to tell me I fucked up his night, in which I asked how I did anything wrong if I was charged for all of our drinks when we offered two different cards. He says, get the fuck out of my face and just write 0 on the tip, Im kind of shocked and write 0, security comes to the right of me and taps on my shoulder. Im trying to figure it out before the guy says stop crying and get the fuck out of here. I leave without signing the debit card receipt.I check with my buddy when I get outside and he was charged appropriately for his drinks, meaning I was charged an extra 13.00 for my order. Because the bartender was shouting and grabbed my receipt customer and merchant copy I dont have my copy. I need help with this one. I have a few thoughts.1. Go to the bar tomorrow, explain what happened to a manager. Hope they can look up the order in their system without a receipt. Hopefully get a refund.2. Call my bank and dispute the charge, which I think will lead to the bar having to prove the transaction was signed and agreed upon? Ignorant to how this works mostly. Get 13 bucks back.3. Call my bank, lie and report my card was stolen, get a full reimbursement, get a new card mailed to me.I know its 13 bucks, but really pissed about the bar mishandling the whole ordeal.Ideas?Thanks  <response>: Do not take option 3. Not worth the risk for 13.
