I wonder how many bars and restaurants would cater to this? So you have a table for two, but only one person is eating or drinking.
So in round numbers, the dining establishment is only getting half of the revenue from that table that they normally might expect to get.
Waiters and waitresses will get only half the tip they might normally anticipate.
If I owned that “resturant” I’d make these pitiful wretches pay for 2 meals and also charge the other patrons extra to watch the happy couple interact with each other and heckle them.
