The other day I was asking the bartender for the WiFi password

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 wifi password?

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