Maybe There Is Something Wrong With Its Pipes?

(We sell plumbing supplies mainly to the trade. We also have a coffee machine, fresh water, cold drinks, etc. A plumber comes in and walks up to the self-serve coffee machine. After about two minutes, I hear him fiddling with the cup and looking confused. I walk over.)

Plumber: “There’s something wrong with the machine.”

Me: “Oh, okay. What happened?”

Plumber: “I pressed ‘espresso’ but all I got was this really small coffee.”

Me: *internal laugh*
