Heli-dum

I work in a floral shop and we are currently out of helium due to the fact there is a helium shortage. We have signs at the check-stand and by our display balloons stating this.

Customer: “I need to get some birthday balloons.”

Me: “I am sorry, sir, we are actually out of helium.”

Customer: “Can’t I just take one of those balloons over there in the display?”

Me: “Actually, those are just filled with regular air so they won’t float away.”

Customer: “Can’t you just make some helium and put it in the balloons?”

Me: *Pause* “Sir, helium is a natural gas; we can’t just make it.”

The customer is shocked by this information.

Customer: “Really? I always thought you guys just made it.”
