Shopkeeper and Customer # 26

Please don't bother me. I am very busy with important matters.
Well, I would like to buy these things.
No. Nothing is for sale.
But this is a shop, everything is for sale.
Not true.
But your things are so sweet. Can I at least buy this?
This? No. I might be willing to sell that, but nothing else.
That? That's so ugly. I might actually be allergic to that.
Tough.
