As a waiter and restaurant manager of almost twenty years, I find it unfortunate that Mr. Hitchens has suffered at the hands of an intrusive waiter. Worse, it seems that he, like many Wine Spectator readers, believe that waiters are out to screw him by over pouring his wine. That sort of paranoia is somewhat inline with other of his writing--but I digress with this little jab.
Proper wine service includes pouring the wine for the customer, but not dumping, or "blasting" a bottle. More on that in a moment. Proper service maintains a level of a 60% glass pour, or a little four ounces at a time, for each customer at all times. Heavy drinkers like Mr. Hitchens are refilled at the same time his guests are refilled. They will be getting less, often just a drop, but everyone's glass stays the same. The result is psychological: all the customers feel they've been served the same amount. This way, Mr. Hitchens doesn't come off as big of a lush as his reputation, and his guests feel they've spent the evening drinking right along side him.
"Blasting" a bottle is, unfortunately, common in the industry. A Riedel Bordeaux or Burgandy glass can hold a full bottle of wine--750 ml. Often, customers believe we are underpouring because the glass is not even a quarter full. It's easy to quarter a bottle among four customers--I've seen waiters do that twice on a party of eight, then leave the empty bottles. That's unprofessional and people who work for me know that if they do it, they will be unceremoniously fired. Good service is hard enough to give in the first place, but being held suspect by your customer is a pain in the ass.
I do find it interesting that Mr. Hitchens wonders where this "vile" practice came from, since its roots are classic French service. It drives home the point that good service varies from customer to customer, and the proper level of service is what's required, no more, no less.
