Off Sushi and Bad Manners

I bought a sushi salmon california combo on the morning of 11th of June. The salmon tasted funny and smelt off. I took it back in the afternoon and spoke to the man making the sushi. His attitude was atrocious. He proceeded to tell me I eat the sushi wrong as I don't eat the soya. I have eaten sushi every week for the past 5 years. I don't eat soya as I don't like the amount of sodium in it! He made out like I was making up that the salmon is off and I was wrong and he was right. I eat raw salmon 3 times aweek so I'm quite clued up on how salmon must taste and smell. I will never buy sushi from them again. It's not because the salmon was off, it's because the tone and attitude this man spoke to me in.
