Wow! Let me get this straight.
Are you trying to say, lelio, that, when you go to eat at a restaurant, you go back to the kitchen and confirm the immigration status of every restaurant worker in the place?
When you go shopping at Safeway, you ask the store manager to give you an affidavit that all his employees have legal immigration status?
You do the same when you hire a bonded contractor to do a construction project for you?
I'm impressed.
