Yes, and more than that: he didn't know what Google Map is. He is 74 and can be excused for that. Fast forward ourselves into our 70+: how many new things we won't know or care about then?
I think everyone here is sympathetic to the idea that a 74 year-old shouldn't have to keep up with every new technology, but you seem to be forgetting the fact that he's running a business. Not knowing what Maps is is fine for a random consumer, but excusing a restaurant owner for not knowing about online map services is basically saying that he's no longer competent to run the restaurant.
...or knowing that he doesn't know about "that online stuff," and hiring someone who does know about it to help him manage it. It's a cost of business.

It's easy for business-minded techies to understand the impact of "that online stuff". It's very likely that a septuagenarian restauranteur simply doesn't fathom its potential impact.
Agreed, and unfortunately for him, his competition WILL understand it. It's survival of the fittest. The fit septuagenarians are the ones who listen to their grand-kids who tell them they have to get "online."
