"It's in all the news: Burger King is merging with Canada's huge coffee chain Tim Horton's and moving its head office north to chase a lower tax rate. Timmy's are big in Canada; they pour 80% of the coffee sold in the country and have thousands of stores. When they come into town, usually on the outskirts near the highways, every coffee shop on Main Street shuts down. They are a cultural phenomenon; the government even shipped one to Afghanistan to boost troop morale. Because of their size, their environmental impact is huge and attracts a lot attention."
