I broke my glasses after getting tossed around on a boat in Alaska. After waiting 2 months to be in a place with optometrists again I popped into 3 Guys Optical in Oakland. They were extremely friendly, helped me right away, and even mentioned possible beer giveaways. After piecing my glasses back together and bending my mangled sun glasses back into form I asked what the final bill was - FREE. I was not expecting that and they certainly will be getting more of my business in the future.
