Most of the time, any public place with a locked Wi-Fi network will let you in on the password (as long as you're a paying customer). But in the event that the place is closed or you're not buying anything and still want access, it's useful to know that many retail and dining operations use the same kinds of passwords. You'll see that the passwords aren't meant to be hard-to-hack or super-secure. They're easy to guess and easy for staff to remember.
In a thread on Reddit's Life Pro Tips, several users contributed their experiences to come up with a list of public password suggestions. Usually, restaurants and stores make their wireless password something related to the venue.
Here's a list of things several users have found to work. If you're stuck without access to the network's password, go down the list and try one or more of these suggestions:
• [the venue's] phone number (with area code, but without hyphens)
• street address
• restaurant/store name
• something popular in the restaurant/store
• location backwards
• default passwords (e.g. "admin," "password," "asdf1234," etc.)
Of course, there's no guarantee that any of these will work, but it's a good place to start if you need after-hours access to public Wi-Fi. If you have any other suggestions, add them to the comments!
