Just in case anyone was curious, we were not successful in getting the truffle mayo at lunch. We asked the CM that delivered our food and she pointed us to the counter with the condiments (which I knew wasn't going to have it). So asked another CM at the counter and he said he didn't know what that was. Tried to explain to him that it was served at dinner and they were still confused. He just ended up squirting regular mayo in a cup for us.
