Me and some friends went to Taco Bell, to get some food. When we went to the window, I gave them my debit card, and I paid for all of the food, then she gave it back to me. Then after the lady gave us all of the food, I asked for a free small drink. She gave me the drink, and she smiled, and the driver just drove out of there fast. He said I just drove fast to add on to the effect. I have like OCD, and I am worried she might go back in the machine, and somehow charge my debit card again, because i am not sure if she heard me say free. So is it possible for taco bell to charge my card again through the machine even though they dont have my debit card, or can they charge me the next time I go to that location, I am just worried. This was all done from drive thru
