How to stop these aggressive people from strong eyeing us?

So there's this place hat sells really good shakes but it's in the middle of a lateeno neighborhood. I take my girlfriend all the time there because she loves it but every time we go the customers in the shop act like they've never seen a well dressed couple in their life. The types here are your average Mexican wannabe cool kids and "gangsters" and "baby momma" heespanas, they won't take their eyes off us and makes us uncomfortable. Yesterday since its in a ghetto area I parked my suv there and when we came out there has your common Honda Civic really close to us, and noticed a dent in the side step, without it it would've damaged the vehicle and it's not even mine, it's my dads g class! I suggested to my so we stop going but she says the shakes are worth it, I honestly have no reason to believe they don't "add" things to our drinks out of hate. Is their anything I can to to stop these lateenos from strong eyeing us?

by the way i am white and my girlfriend is asian if it matters, maybe its race related?
