Good. Leave.
I found this sentiment offensive. It should say "Good. Then go home to Mexico."
Otherwise he might think he has license to go to Canada or somewhere else.
Yesterday I stopped in at a local restaurant named "Azatlan." I asked the owner what the name meant. He said it was a town in Mexico around Mexico City. I have yet to find a town of that name of any size in Mexico, although there is one tiny one that comes up.
On the counter was a business card for a company called "Conquest." Probably all a coincidence, but the hostility in that restaurant against this gringo was palpable.
