I'm sorry this happened and he was rude/abusive. Sometimes we have to learn lessons the hard way. Now you know to avoid him. Even though you work in the same place, just act like you don't care and go on with business. You don't need to feel embarrassed ..he's the one's who mean. Don't care about what he says or does - he's not a good person to be around - he's insensitive and mean. You can't let a person like this determine your mood....he's not worth it.
