Ormiston, in answer to your question, "What times do I go to the coffee shop", I have gone at all times of the day and all days of the week. I've noticed that the make up of the crowd changes depending on the time of day and day of the week. Early in the mornings, it's packed with people on their way to work. Around mid day, it's packed with high school kids on their lunch break. Weekend mornings, it's largely a middle aged crowd. Weekend mornings are good times to meet people of my own age and interests.
Some years ago, when I was new in town, I choose that particular coffee shop because it sold the cheapest cup of coffee around. Unknown to me, the coffee shop was the hang out of kids from a nearby high school. Since I would get to the shop around noon, when the kids did, the first 100 or so people I met in this town were all 18 or under. I despaired of having a social life with people my own age. But then a strange thing begin to happen. The kids decided I was cool, and started to introduce me to their single and divorced mothers. Moral of the story: don't be quick to discount meeting anyone. Even people you aren't interested in dating will sometimes introduce you to someone you are interested in dating.
