My best dating apps lately have been Trader Joe's and Ducky's Car Wash.
I wear aloha shirts every day, and nearly every time I go to TJ's, someone asks me where they can find a particular item. It may be a guy or a gal, but I am always happy to help a neighbor find what they need.
That is not the reason I wear aloha shirts. I just love these shirts! Every spring I get the Cooke Street shirts at Costco, one of each new pattern.
One time at the Menlo Park Trader Joe's I was talking with the guy restocking the freezer section. He said, "Nice aloha shirt! I bet people sometimes think you work here."
Sure enough, a minute later a young lady walked up to me and asked if we had organic bread. I walked her over to the bread section and pointed out the organic breads.
Later I caught up with the freezer guy again and told him "you were right!"
Ducky's, for those unfamiliar, is a car wash with several locations on the SF Peninsula. Even if you just get an exterior wash, after you go through the tunnel they hand dry your car.
There is a waiting area outside with a dozen chairs, and it takes 5-10 minutes before your car is ready.
And you never know who you might run into there!
The key to this, of course, is to be outgoing and friendly, and open to surprises.
