A Senseless Act, Just The Wrong Sense

I am a bus driver. My ticket machine and card reader are not functional today and everyone is getting a free ride. Even so, due to traffic, I am still running late. I pull up to the bus station and let everyone on. 

Me: *To every passenger* “It’s free; just jump on!”

Everyone thanks me and goes to sit down. I am repeating the phrase the whole time as people are getting on. But then, one kid and his mum get on and the kid just keeps trying to tap his card. 

Me: “It’s free; just jump on.”

Me: “It’s not working.”

Me: “The machine is not on.”

Me: “It’s not on.”

Me: “IT’S NOT ON!”

Mother: “Well, that was rude!”

Me: “What was rude was me saying it four times before having to raise my voice to get through.”

Mother: “I’m vision impaired.”

Me: “That doesn’t affect your hearing.”

Mother: “I’m going to complain.”

Me: “No worries. Enjoy.”
