Vein-y Prawns

I don't know why I keep doing this to myself, but I do. The hubs and I ended up at the Jurong Point Fish & Co for lunch today and it was a really bad batch of prawns. The chef didn't clean the veins out, so when it came all grilled to me, the veins were sticking out thick and black. Used my warm water to wash the last few... that's how bad it was. Luckily the waiter asked me to fill in a survey... now I wonder if they do read their surveys as this is not the first time I'm complaining about the vein-y prawns!
