This seems to be the busiest and most successful frozen fish stall in the market. It usually occupied by high numbers of older clientele who looks for the best deals of the day. There is a relatively limited range of mainly frozen fish and seafood for very very competitive prices: cod fillets, swordfish steaks, salmon, hake etc. The is a saw on all the time dividing the stone-hard pieces of frozen fish and creating the characteristic scary sound around this stall, I think you might call a good example of an original sound marketing although I am not sure the other marketmen like it.
