Try to sell him... something?

Your not to sure what you could possibly sell to a goblin, especially since you have nothing to sell, But this never stopped you before. You put on your best winning smile, and business accent to sound more exotic. "Hello my friend. your be interested in buying?" You ask. The goblin was a little taken back by your sudden appearance. "Interested in buying what?" He replied in a squeaky voice that was like nails on a chalkboard. "Well friend it a special deal you see. Once in a lifetime. One that so grand I can't even describe to you how wonderful it is." You said doing your best to make it sound grand. "What is it your trying to sell me?! Tell now or leave!" The goblin screeched, clearly getting annoyed. You knew at that point you had him in your hands. "You see I'm sell 10% of an up and coming company. For a small fee of 2,000g you could receive a nice payment of 100g every year from any bank." You explain trying your best to making the amount so outrageous that any respectable merchant wouldn't wouldn't dream of take it. The goblin thinks for a moment and surprisingly accepts the deal. Your kobold stop with her hand still in the goblin pockets and slowly turns her head in utter disbelief at how stupid this goblin is. Even you where dumbfounded by this and quickly signaled amethyst to abort. She nodded and retreated just as the goblin reached in to give you his whole life savings. Once you had the money in hand, the goblin chuckled to himself. "You stupid lizard! You now work for me or free, and I make 100g at bank!" The goblin laughed to himself as he ran off before you could change your mind.
