Selling Bad Grammar

I found this sign plastered on a food vendor selling Tibetan momos. There is no telling precisely what it's trying to convey. There are, however, a couple of ways of interpreting this.

A sign on a food vendor, in Queens, New York.

1. So far, they've been passing off water as soup to their customers. But from the first of December, they promise to make amends and sell soup.

2. Their soup, thus far, has been so watery and dilute (with the two in the ratio of 95% and 5%) that their customers took it to be hot water. Come the first of December, however, they they're will change the proportion such that the new concoction is slightly thicker and hopefully more palatable.
