When you go to a Coffee Bean and Tea Leaf shop, you can use the Wifi there for free. What you need is a password. Usually shops say it's 12345 or 22222. Coffee Bean does better. The use their product names, like cafelatte or iceblended. Since many people more likely remember the internet password than a coffeeshop product, its a nice way of marketing.
Totally different does actually the Korean Company Angel-in-us. Ok, the name itself is silly, but their branch at Nguyen Hue Street does even better. See the screenshot of available networks and guess what the Angel-in-us one is.
