Wouldn't trust the fucker's food, either. If he can lie about a pizza being vegetarian when it has ham in, or tell vegetarian diners that something with chicken stock in is vegetarian, what else will he lie about?
"One of the volunteers who agrees to take part says that he has been a vegetarian for eight years. Ramsay replies that the restaurant's chefs have prepared a vegetarian pizza and gives him one to try. After the volunteer - identified only as "Bob" - has eaten the pizza, Ramsay tells him: "Unfortunately, that pizza has got a lot of mozzarella and tomatoes, but underneath all that there is parma ham."
The vegetarian complains to Ramsay that he has played a "mean" trick on him, but Ramsay jokes that he "hasn't come out in a big rash". He is then filmed laughing at the man and asking him if he would like some more, while telling the restaurant's chefs that they have "converted a vegetarian". As the volunteer hurries out of the restaurant, Ramsay calls out after him, "Good luck with the Vegemite!"".
Ramsay's pizza joke outrages vegetarians
On another occasion:
"he confessed in an interview to having fed a dish to a vegetarian party that contained chicken stock."
