The Wifi Password

A man goes into a bar in the airport and asks the bartender what the password is to their wi-fi.

Bartender: You need to buy a drink first.

Me: Okay, I’ll have a coke.

Bartender: Is Pepsi okay?

Me: Sure. How much is that?

Bartender: $3

Me: There you go. So, what’s the wi-fi password?

Bartender: You need to buy a drink first. No spaces, all lowercase.
