Tim Hortons review: coffee

Almost every night not long before closing time I go to get coffee I take dark roast and every night I am told there is no dark roast on am I willing to wait and again every night I say yes I am willing to wait tonight they were not happy about having to put on a pot of something that should have already been there as far as I'm concerned they should have a pot of both on at all times and stop getting angry about having to do your job if you had been doing your job the coffee would have been already there
