Tim Hortons review: drive through person who is taking order

At this address the past 3 times I have been there, this morning weds oct 9 at 10am being the most recent. Whichever lady is taking orders at the drive through is extremely rude and impatient even when my ordering is efficient. She interrupts and cuts me off when I'm ordering and this has happened the last 3 times. This time once she interrupted me I just cancelled my order and left. There is zero chance I will be returning to that location as long as she is employed there
