I agree that this is at present an "industry standard". There is one legitimate exception but you'll find it in precious few restaurant venues (although this will change with time).
Here and there a few forward thinking restaurateurs have developed relationships with some of the more progressive independent roaster and begun offering a "coffee menu".
This will typically include some of this season or last season's best estate varietals - in some cases "CoE"
Cup of Excellence winners. In most cases the brewing method offered will be individual press pots and the price per serving does not include "refills".
Restaurant Eve in Alexandria VA and Carriage House Cafe in Ithaca NY are among a handful of dining establishments offering such an option.
At the $2.50 to $4.00 price point that most fine dining establishments charge for coffee it's a reasonable expectation that there's no charge for refills. If they are paying $8.00 to $10.00 per pound for a high quality coffee at wholesale prices (not award winning - just high quality) the cost of goods is 12 to 15 cents for each 5 to 6 ounce cup.
Add in the capital expense and depreciation of a brewer, electricity, water etc. .... and there is still an extremely healthy markup - even if you provide multiple refills.
But the sad reality is that many "fine dining" restaurants aren't seeking out what many of us in the trade regards as exceptional coffee. I'll hazard a guess that they are also not paying attention to process control, freshness and stock rotation, brew temperatures etc.
I may be preaching to the choir here (in some cases) but some very good highly regarded restaurants still serve some very mediocre coffee. I find it truly bizarre that establishments sourcing the finest quality ingredients and ensuring that those food products stand out and display the best aspects of their inherent nature.... pay so little attention to a product that is often the final note of a diner's evening.
That's a shame.
