But Subways, at least here in Australia, are usually empty or almost empty. McDonald's are almost always packed.

Aaaah, Subway. Used to be great, but an 8 inch sandwich(four pieces of cucumber wide) on an 11 inch piece of bread that has doubled in price, with the quality constantly dropping...I used to eat there every day. Not been for three years, now.

Subway is the closest place to buy food to my office, so I only eat there on days when I forgot to bring lunch and I'm pressed for time. That's always a bad day.
