There are times in life when dating happens with no planning on the part of either party, but that does not mean it is a bad idea. Two people might be stuck in line at a restaurant, and they could agree to share a table. Their conversation while waiting could turn up some mutual interests, so they might decide that a spontaneous meeting is worthy of a date for the rest of the evening. While there is no guarantee a relationship will ensue, spending time with someone new might be just what they need to make life more interesting.
Dinner is a good time for people to relax at the end of the day, and many of them prefer relaxing conversation during the meal. They find it helps them let go of the cares of the day, but it makes them aware of the possibilities they can enjoy during their evening hours. A couple who has met while standing in line at a favored eatery will find this formula can work with strangers and friends.
Relaxing together could provide them with an opportunity to explore mutual interests, so the conversation could be a good one. If one of them has plans for the evening, they might choose to cancel them to remain with a new person. Neither of them might have any plans, nor are they interested in ending their conversation. Retiring to a coffee shop for further conversation might suit both of them, and they could eventually agree that a more formal date would be a good idea.
Dating is about meeting new people and getting to know them, so there is nothing wrong with a spontaneous date. For those who are seeking a permanent relationship, it seems to matter little what circumstances occur for that first date. Finding the right person could be as easy as waiting in line for dinner.
