I visited a coffee shop where the Wifi password was wedonthavewifi.
It was a very frustrating conversation with the cashier.
My Wifi password is "writtenontherouter"
And I let all my guests walk to the router and let them unsuccessfully try to use the initial password until I tell them it's literally "writtenontherouter".
'what's the Wifi password?'
'Its for security'
'Haha, yes, I know that. But what's the password?'.
'No, it's 'forsecurity'. All one word, lower case.'.
"Dad, my computer can't find the Wifi printer anymore... I renamed it to Bob Marley, same password."
"Why Bob Marley?" - he asked.
"Because its always jammin"
I asked the bartender for the WiFi password but he told me to buy a drink first. So I ordered a Moscow Mule and asked him again. He handed me a card with the password. It said:
"Buy a drink first" ... no spaces, all lowercase."
