A guy walks into an airport bar and asks the bartender for the wi-fi password.
Bartender: «You’ve got to order a drink first.»
Me: «Alright, I’ll take a Coke.»
Bartender: «Is Pepsi fine?»

Me: «That works. How much?»
Bartender: «$3.»
Me: hands over the money «Great, now what’s the wi-fi password?»
Bartender: «You need to buy a drink first. No spaces, all lowercase.»
