There's a LOT of homeless in SFO pooping in the streets that would love the $5! Sure, they're tapping into that, that's partly what they're there for. So sad!!
How would you know just by looking whether someone is a ME'r or Mexican or from Honduras??
Honestly, they all have similar features. I'm from ME (Christian) and I've ALWAYS been mistaken for a Hispanic.
And how much would that cost us??
You're talking an invasion of 50k people. Nope! I don't want my tax $$$ going for that.
