Tim Hortons review: This is to the lady that served me in the drive thru

At 3:00am September 1st I went to the drive Thur at timhortants in Edson Alberta by sobeys. I was served my a young girl who look like she was by herself as I told my first drink I wanted I started to ask for the next drink but was cut off before finishing what I was saying. she replied with "anything eles". I told her yes I wanted a French vinalla... again cut off with " That's it"? Me with only a half a shot of exspresso her "that's it"? Yes but please only a half a shot. I get up to the window and wanted to make sure about the French vanilla that it had only a half a shot of expresso as I have alot of issues with having to bring back my drink not done right because they seem to not listen to what you want and just rush you and make your order wrong. So I ask her one more time as I'm looking at her is there only a half a shot of expresso in the French vinalla her response was very Rude and very unprofessional her response was "OBVIOUSLY " with eye roll I could not believe it. I asked for her name and she refused so I told her I well be contacting the manager about her poor costumer service her reply ya okay.
