Tim Hortons review: drive thru window car

Was just at huntsville ontario hwy 60 tim hortons as we went thru the drive thru we ordered everything bagel med. French vanilla and 2 lg coffees (french vanilla and bagel was for our 12 yr old son) as we were getting our sons attention to grab his hot beverage the woman working the window very rudely yells "here take ur bagel" when I chimed in from the passenger seat we were trying to get our sons attention in the back and asked for his name (he was not wearing a name tag which I thought was part of the uniform) he refused to give me his name and ignored us except for quietly handing my husband out 2 lg coffees. It was at 4:57 pm on october 24 I am very upset with how he raised his voice at a customer and I think staff there need to take a customer service course so they know how to have positive interactions with customers.
