I highly suggest going to the McDonalds on McClintock and Elliot, aside from always getting my order correct and fill my soda all the way to the top but they also hire cashiers who know how to count change correctly.
At this location, there's countless times that the concept of fast food is waiting 20 minutes only to get stale bread, cold french fries and the genius giving change cops an attitude when you correct how much change he owes you. This location is in desperate need of a severe Ronald ass kicking! Shame on the management, can you even try to care about your customers.
