Smashing Glass Puns

It's unclear what happened

"Hi. My name is Robert if you need anything."
"Great. What's your name if we don't need anything?"

Robert: "Would you like more soda, sir?"
Dad: "Yes. Please."
Robert takes the glass and walks away to refill it.
Dad: "That's less soda, not more!"

Me: "Let's get more [tortilla] chips."
Dad smashes the last chip into hundreds of pieces. "There. More chips."

Edit: When the lights in the restaurant are dimmed.
Dad: Uh oh! Prices just went up!
(Who ordered the ambiance?)

I dropped a glass and it broke, sending pieces of itself across the whole of the kitchen.

My mum hears this and responds, 'are you having a smashing time?'
