First dates should be low stakes, don't put to much pressure on anyone. You really just want a quick chance to know a little more but a little goes a long way. Each person should be able to call it quickly when they discover the other person smells bad or whatever. Ideally stick with a drink, coffee, lunch, a walk or picnic in the park. You want to be able to talk with the person and but also quickly cut it off if you find out they voted for trump or something crazy.
