Well played, barman
When there’s free Wi-Fi, people go nuts. Even if there’s not enough bandwidth to go around, people would much rather sit in a busy café or bar with bad internet than be there without it. One of the first things we ask for when we enter a bar is the Wi-Fi password.
When this patron asks for the password, the bartender responds, “you need to buy a drink first.” He then buys a Pepsi before asking for the password again, to which the bartender responds with the same answer. “No spaces, all lowercase.” Outstanding move there, bartender. Free Wi-Fi is free only if you purchase something, after all.
