This video (link), which I don't endorse, provides a "parable" regarding how Starbucks would look if it were marketed like a church. While there are a number of amusing aspects to the video, the apparent underlying message (that the church, to be successful, should be more like Starbucks) is wrong.
Yes, there are bad things that go on in churches. Nevertheless, the point of church is not simply so random folks off the street can come in, get served, and go. The church is a fellowship of believers.
Yes, there are many pulpit crimes taking place in churches throughout the world. There are many inappropriate ways that churches handle new visitors. Despite that, though, the point of church is not simply to purvey a commodity as a coffee shop does: it is not designed to help one relax and unwind. It is not a place where a person should feel anonymous and simply a part of the crowd. It is a place where discipline is exercised and fellowship is nurtured and fostered.
The services of worship are about serving and worshiping God, not the congregants. We do want people who visit to make their stay permanent. But we do not wish to do so by giving up our zeal for God, the reality of our fellowship with one another, or the push for proselytizing.
Give up any of those and we might as well run a coffee shop instead.
