Leprousy joke

One day a leprous man walks into a restaurant.  He is used to being turned away so he is ecstatic to find that the restaurant assures him that they do no discriminate.

He tkaes his seat and oders but is disturbed to find a woman, not 10 feet away repulsed by something and vomiting.  He quickly calls over the waiter and asks if he should leave so as not to disgust the other patrons. But the waiter assures him that she is not disgusted by him.

Less than 10 minutes later, a man at the next table also begins to vomit as his table follows suit. Once again the man doesn't want to disrupt these people's dinner so he asks if he is a nuisance.

The waiter says " Sir i assure you that you are no problem at all. These people are throwing up because the man seated at the table behind you is dipping his bread in your neck..."
