Elementally Flawed

Me: *answering a phone call* “Hello, you’ve reached [Gift Shop]. This is [My Name] speaking.”

Caller: “Hi, do you sell t-shirts?”

Me: “Yes, we do; our t-shirts are $24.99.”

Caller: “Do you have any periodic table t-shirts?”

Me: “No. Unfortunately, we don’t have any periodic table ones.”

(I list our available designs for the caller.)

Caller: “So, do you have any periodic table shirts?”

Me: “No, only the designs I mentioned. Sorry.”

Caller: “And how much are they?”

Me: “$24.99.”

Caller: “And you have a periodic table one?”

Me: “No, we do not, I’m afraid.”

Caller: “Okay, so what sizes do you have?”

Me: “At the moment we have sizes 10, 12, and 14.”

Caller: “Do you have any that would fit me?”

Me: *pause* “No.”
