Personally I think its a bogus reservation policy.

I believe you should either take reservations, learn how to work them to your and your patron's advantage or don't take them at all.
If their walk in business is strong enough to warrant an hour wait, then I don't understand they wouldn't take reservations for 4 tops or deuces. Why are they even bothering to answer the phone to take reservations at all? It doesn't make since to me why they couldn't take reservations for everyone until every table is booked. Give them 15 minutes to show up, otherwise you lose your table. Tell everyone that is your policy when they make their reservation. Even if you don't book them all you could still have your walk-ins wait around at the bar until something opens up with a no-show, fast eaters, etc.
I think the problem might be is that they don't want to tell some one that
no we can't take you because we are booked at a certain time. Like 7:00 on a Friday when the entire world wants to eat. So instead of having to say
no, they just have everyone waiting around for an hour when they could have just taken 8:00 reservations
Here's what you could do, Make the reservation for six at your requested time, Show up with your other couple and have them seat you immediately, telling the hostess that the rest of your party will be arriving shortly. Once you get seated, tell your server that the other party had to cancel at the last minute.
