For those who have everything they need, hunting through small stores could be a hobby that takes their mind off the stress of work. They could find that a shopping trip with no particular goals suits their need to do something without being concerned they will find something. These are the people who wander through small shops, and they are not always looking for something to purchase. They could be seeking ideas for decorating their home, or they could be just killing a few hours.
When goals are not the focus of an activity, people tend to relax a bit more than usual. They are able to notice things they might have missed otherwise, and that can include a potential date. A person wandering through an antique store could find something more interesting about the other customers than the items on display, and their relaxed demeanor could lead the two to strike up a casual conversation.
If the talk becomes interesting enough, the two might decide to stop off somewhere nearby for a coffee or a drink. Their conversation could be interesting enough to lead them down the road of exchanging some personal information. Enjoying the relaxed atmosphere could provide them with the opportunity to notice they like chatting together, and it could eventually lead them to a more formal date. It could be the start of a romance, or they could become just friends for life.
Modern life often tends to put people on edge, and they are in so much of a hurry that they can miss meeting people who might be compatible. For those who have no particular goals in mind for even a few hours, it could be a chance to find someone for the rest of their life. Meeting in this unconventional way could even take them to the conventional thought of getting married and raising a family.
