There are some seafood processing shops at the entrance of the market, so don't worry about the lack of money. When buying seafood, each store first asks for the unit price. If the weight of the processing shop is correct, it is definitely no problem. There are also a lot of fruit stalls at the door of the market that are cheaper for you to eat.
