Tim Hortons

Went thru drive thru last night around 515 and ordered 6 home style biscuits and the young guy kept over charging me, I explained what I pay for them. He proceeded to tell me that they were $3.27 for three. I ordered six and he told me the price was $6 something. I told him that I pay $3.79 he then told me where do I find that on the register. I told him that I dont know that I dont work there, I waited close to 15 minutes by the time I got my order. I think that the workers need to be trained more. He took three more orderes while he was trying to figure out my order.
