Do I really have to pay for this drink?
Why would you not pay for your drink?
I can't come up with a way to pay for it, I can't afford wasting that type of money on drinks.
Not wanting to waste money is fine but you already ordered the drink. Not paying for it now would be stealing and you know better than that. You could get banned from coming here or they could even call the cops just because you refused to pay for your drink.
No, it's not stealing. Theoretically, the bar should keep an eye on the cameras and make sure I'm not stealing. It's their fault if they don't see me.
Do you really think it's not stealing if you don't get caught? Maybe you should just order something more affordable that you have the money for. Won't you feel better when you know that you have paid for everything that you have ordered?
