The Tale of the Shoe Repair Machine

Above our row of dryers there are stick-on letters describing our other services that we provide, such as "Leather Cleaning", "Shoe Repair", "Dry Cleaning", and "Alterations". A man walked in one day asking how much it would cost for us to dry clean a pair of pants. I told him. He asked if he could get them done in an hour and I told him no, since the dry cleaner had already come and gone (we send our stuff away to be dry cleaned).
"Couldn't you just do it there?" He points to my right where our row of dryers is.
"Uh, where?"
"Over there. Where you do the dry cleaning."
Still confused. "We don't do the dry cleaning here, we send it away."
"But it says you do dry cleaning here." Again he points. "Isn't that the machine? It says so right above it."
I begin to understand. Because the dryer says "Dry Cleaning" above it it must be a dry cleaning machine! "Oh, no, those are our dryers. They aren't dry cleaning machines."
"Oh, okay." He leaves.
Now, I can perhaps drop my intelligence enough to understand why somebody could think that a machine that quite resembles a dryer could dry clean clothes, as even I am not too familiar with the dry cleaning process, but above our dryers is also written "Shoe Repair" and "Alterations". Could somebody think that a machine that quite resembles a dryer could magically fix one's shoes or mend one's pants if placed inside? Of course not. So why would a person think that a machine that quite resembles a dryer could dry clean clothes? Perhaps I will never know. . .
