Tim Hortons review: Staff name Susan

I will like to file a complain the staff of tim horton name ms susana located at store 9251 woodbine ave l6c 1y9 ontario canada. I ordered ice cap every single day on this store thru online and pick up at the window and I have no problem until this morning april 28 at around 11am susana told me to go to drive thru, I told her I dont have a car thats why I ordered online and she insist its not safe to go on the window side, again I said I dont drive and I dont have a car and im ordering thru online everyday, she never stop talking, does she knows the online ordering for customers who has no car and the drivers with the big track that cant pass on the drive thru? does shes knows their business priority "CUSTOMER" she should accomodate the customers like me. she should not work on the drive thru counter if she doesnt know how to handle customers concern.
